Leg pain after hysterectomy is not unusual, though its frequency depends on what is causing it. The most well-documented cause, nerve compression from surgical instruments, has been reported in roughly one in ten patients undergoing abdominal hysterectomy in some studies. Other causes range from positioning during surgery to blood clots, and the type of hysterectomy and how long the operation takes both play a role in individual risk. Most cases resolve within weeks, but the range of possible causes means that new or worsening leg pain after surgery always warrants attention.
Femoral Nerve Compression During Surgery
The single best-studied cause of leg pain after hysterectomy is injury to the femoral nerve, the large nerve that runs through the pelvis and down the front of the thigh. During abdominal hysterectomy, surgeons use self-retaining retractors to hold the incision open and keep the bowel out of the way. These retractors can press the femoral nerve against the pelvic sidewall, cutting off blood flow and damaging the nerve. One prospective study found that femoral neuropathy developed in about 12 percent of patients who had an elective abdominal hysterectomy, and the problem was consistently linked to retractor use.1Obstetrics & Gynecology. Iatrogenic Femoral Neuropathy Subsequent to Abdominal Hysterectomy: Incidence and Prevention
Cadaver studies and clinical investigations have confirmed the mechanism: the retractor blade physically compresses the nerve against bone and muscle, producing ischemia (loss of blood supply) in the nerve itself.2JAMA. Femoral Neuropathy—A Neurological Complication of Hysterectomy Different retractor types have been implicated, including the commonly used Balfour and Bookwalter models.3American Journal of Obstetrics and Gynecology. Prevention of femoral nerve injuries in gynecologic surgery The result for the patient is typically weakness in the thigh, difficulty straightening the knee, numbness over the front of the leg, or a combination of all three. The pain can range from a dull ache to a sharp, burning sensation.
This particular risk is most relevant to open abdominal hysterectomy rather than laparoscopic or vaginal approaches, because those smaller-incision methods do not require the same large retractors. That said, femoral neuropathy has been reported after vaginal hysterectomy as well, where it appears to involve different compression mechanisms. One case report documented bilateral femoral neuropathy after a vaginal procedure, confirmed by nerve conduction studies showing damage to both femoral nerves.4PubMed.

How Surgical Positioning Affects the Legs
Many hysterectomies, especially vaginal and laparoscopic-assisted procedures, are performed with the patient in the lithotomy position, where the legs are raised and supported in stirrups. This positioning stretches and compresses nerves in the legs in ways that can cause postoperative pain, numbness, or weakness. A study of 1,000 patients undergoing surgery in the lithotomy position found that about 1.5 percent developed a lower-extremity nerve problem afterward.5Anesthesiology. Lower Extremity Neuropathies Associated with Lithotomy Positions The nerves affected included the obturator nerve (inner thigh), the lateral femoral cutaneous nerve (outer thigh), the sciatic nerve (back of the leg), and the peroneal nerve (below the knee near the outer calf).
Cadaver research has helped clarify why certain positions are riskier. When the hips are spread apart (abducted) to 30 or 45 degrees, strain on the obturator nerve increases sharply. Interestingly, adding hip flexion at the same time seems to relieve some of that strain, which has led to practical recommendations about how to position patients in stirrups.6Clinical Anatomy. Effect of lithotomy positions on strain of the obturator and lateral femoral cutaneous nerves The longer a patient remains in the lithotomy position, the higher the risk, because prolonged pressure on any nerve eventually impairs its blood supply.
From a practical standpoint, the kind of leg pain caused by positioning tends to show up immediately or within the first day or two after surgery. Patients sometimes describe it as a “dead leg” sensation, foot drop (difficulty lifting the front of the foot), or numbness along a specific strip of skin on the thigh or calf. These patterns help clinicians distinguish positioning injuries from other causes.
Blood Clots in the Legs
Deep vein thrombosis, a blood clot forming in the veins of the leg, is a known risk after any major pelvic surgery. Hysterectomy patients face this risk because surgery triggers the body’s clotting cascade, immobility during and after the procedure slows blood flow, and the operation itself can involve manipulation of blood vessels near the pelvis. A large analysis of more than 20,000 hysterectomy patients found a postoperative blood-clot rate of about 0.5 percent. Among those who developed clots, roughly four in ten had a clot confined to the leg veins, while the rest involved clots that traveled to the lungs.7PubMed Central. Risk Factors for Venous Thromboembolism After Hysterectomy
Several factors push that risk higher. The same study found that abdominal hysterectomy roughly doubled the odds of a clot compared with non-abdominal approaches, and that each additional hour of surgical time raised the risk further. A body mass index of 35 or above and having cancer as the reason for surgery were also independent risk factors.7PubMed Central. Risk Factors for Venous Thromboembolism After Hysterectomy In gynecologic surgery for cancer specifically, the DVT rate climbs considerably; one study found postoperative DVT in about 11 percent of patients with malignancies, with age over 60 and the need for blood transfusion flagged as independent risk factors.8Thrombosis Journal. Prevalence and risk factor of post-operative lower extremities deep vein thrombosis in patients undergoing gynecologic surgery
Leg pain from a blood clot typically starts days to weeks after surgery rather than immediately. The classic signs are swelling in one leg, warmth, redness, and pain that worsens when standing or walking. Clots have been reported even after minimally invasive approaches: one case involved a woman who developed extensive clotting across multiple veins in the left leg twelve days after a laparoscopic hysterectomy for heavy menstrual bleeding.9PubMed Central. Deep vein thrombosis following laparoscopic hysterectomy in a nulliparous woman The takeaway is that a less invasive surgical approach reduces but does not eliminate the risk.
How Blood-Clot Prevention Works
Because the consequences of a missed clot can be severe, most surgical teams use some form of prevention. A large nationwide cohort study found that postoperative heparin (a blood-thinning medication) reduced the risk of clots by about a third in hysterectomy patients.10PubMed. Venous Thromboembolic Complications to Hysterectomy for Benign Disease: A Nationwide Cohort Study Other prevention strategies include compression stockings, intermittent pneumatic compression devices on the calves during and after surgery, and early ambulation once you are cleared to walk. Your surgical team will decide which combination fits your risk profile. If you have any of the higher-risk features discussed above, you are more likely to receive medication-based prevention rather than mechanical methods alone.
Well-Leg Compartment Syndrome
This is the rarest cause on this list, but it deserves a mention because it is also the most dangerous. Well-leg compartment syndrome happens when prolonged pressure on the leg during a lithotomy-position procedure causes swelling inside the tight compartments of muscle in the lower leg. Because these compartments are enclosed by fascia that does not stretch, the swelling cuts off blood flow to the muscle and nerves. It is recognized after urological, colorectal, and gynecological procedures performed in the lithotomy position.11PubMed Central. Well leg compartment syndrome after pelvic and perineal surgery in the lithotomy position
The consequences can include kidney failure from muscle-breakdown products entering the bloodstream, permanent nerve damage, and in extreme cases limb loss or death.12PubMed Central. Prevention of well-leg compartment syndrome following lengthy medical operations in the lithotomy position Symptoms include severe calf pain that seems out of proportion to what you would expect after a pelvic operation, pain that worsens when the toes are stretched, and a feeling of tightness or hardness in the lower leg. Some gynecological teams now use perioperative checklists specifically aimed at reducing this risk, particularly for operations expected to last several hours.13BJOG: An International Journal of Obstetrics & Gynaecology. ‘Well‐leg’ compartment syndrome associated with gynaecological surgery: a perioperative risk‐reduction protocol and checklist
The practical point for patients: if you develop severe, escalating calf pain in the first day after surgery, especially after a long procedure done in stirrups, it needs urgent evaluation. This is not a “wait and see” situation.
What Intraoperative Prevention Looks Like
Surgical teams have several tools to reduce the risk of positioning-related nerve injuries and compartment syndrome. Padding around the peroneal nerve at the side of the knee is standard in many centers. Avoiding extreme hip flexion reduces compression of the femoral nerve, and keeping operative time as short as possible lowers the risk across the board. Friction-based padding materials prevent the patient from sliding on the table during a head-down tilt, which is common in laparoscopic pelvic surgery.14PubMed Central. Patient positioning during minimally invasive surgery: what is current best practice? None of these measures eliminates the risk entirely, but together they substantially reduce it.
Chronic Pain After Hysterectomy and Where It Shows Up
Most discussions of post-hysterectomy pain focus on the pelvis and abdominal incision, but the pain does not always stay in one place. A study that specifically tracked chronic postsurgical pain after abdominal hysterectomy found that about half of affected patients had pain at the scar, while roughly 39 percent reported groin pain.15PubMed Central. Chronic postsurgical pain and neuropathic symptoms after abdominal hysterectomy: A silent epidemic Groin pain can radiate into the upper thigh and be difficult to distinguish from a hip problem or a nerve issue. Low back pain was the least commonly reported site in that study, at under 4 percent, though the researchers noted that more than one pain area was common in the same patient.
The neuropathic quality of this pain is worth noting. Patients often describe it as burning, tingling, or shooting rather than the deep ache of muscular pain. When chronic pain develops with these characteristics, it points toward nerve involvement, whether from direct surgical injury, scar tissue trapping a nerve, or changes in how the nervous system processes pain signals after tissue damage. This distinction matters because neuropathic pain and musculoskeletal pain respond to different treatments.
Recovery and Prognosis for Nerve-Related Leg Pain
The encouraging news is that nerve injuries from hysterectomy usually recover. A prospective study tracking pelvic nerve injuries after gynecologic surgery found that complete resolution of symptoms occurred in about 91 percent of patients. The median time to recovery was roughly a month, though the range was wide, from as little as a day to as long as six months.16American Journal of Obstetrics and Gynecology. Pelvic nerve injury following gynecologic surgery: a prospective cohort study The speed of recovery depends on the severity of the original injury. A nerve that was briefly compressed and lost blood flow temporarily often bounces back in days. One where the actual nerve fibers were damaged (but the outer sheath stayed intact) takes longer, because the nerve has to regrow along its existing pathway at a pace of roughly a millimeter a day.
If leg weakness or numbness has not improved at all by six to eight weeks, nerve conduction studies and electromyography can help determine how severe the injury is and whether recovery is on track. These tests measure the electrical activity of the affected muscles and how quickly signals travel along the nerve. They are most useful at the six-week mark rather than immediately after surgery, because early testing can underestimate the extent of the problem before the body has had time to declare whether the nerve is healing.
When Hysterectomy Resolves Pre-Existing Leg Pain
In a twist that surprises some patients, hysterectomy can actually fix certain kinds of leg pain rather than cause them. Endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus, occasionally invades nerve tissue around the spine or pelvis. When it does, it can produce sciatica, the shooting pain that runs down the back of the leg, often in a cyclic pattern that worsens with menstruation. One documented case involved a patient whose chronic back and leg pain resolved completely after a hysterectomy with removal of both ovaries, once the underlying endometriosis had been diagnosed.17Elsevier / World Neurosurgery. Cyclic Sciatica and Back Pain Responds to Treatment of Underlying Endometriosis: Case Illustration
This is relevant because if you had leg or back pain before your hysterectomy and it persists afterward, the surgery may not be the cause. The underlying condition that prompted the surgery could still be the culprit, especially if the endometriosis was not fully excised or if the pain turns out to have a separate musculoskeletal source. On the other hand, if cyclical leg pain disappears after hysterectomy, that is a strong clue that endometriosis was driving it.
Restless Legs Syndrome and Hormonal Changes
Restless legs syndrome, the uncomfortable urge to move the legs especially at night, has a complicated relationship with hysterectomy. When the ovaries are removed along with the uterus, the sudden drop in estrogen and other hormones appears to raise the risk of developing restless legs. A study from the Mayo Clinic found that bilateral oophorectomy was associated with a higher risk of later restless legs diagnosis, and this association held even after accounting for iron deficiency anemia, which is itself a known trigger for restless legs.18PubMed Central. Association of Premenopausal Bilateral Oophorectomy With Restless Legs Syndrome
Interestingly, iron deficiency anemia was actually less common after oophorectomy than before it, because removing the uterus eliminates menstrual blood loss. That rules out anemia as the explanation for the higher restless legs risk and points instead toward the hormonal shift itself.18PubMed Central. Association of Premenopausal Bilateral Oophorectomy With Restless Legs Syndrome If you had a hysterectomy with ovary removal and notice restless legs symptoms starting weeks or months later, this connection is worth raising with your doctor. The symptom profile is different from nerve injury pain: it is more of a creeping, crawling, or aching sensation that improves with movement rather than a fixed numbness or weakness.
When to Seek Urgent Evaluation
Not all post-hysterectomy leg pain is created equal, and some presentations warrant immediate attention. You should contact your surgical team or go to an emergency department if you notice any of the following:
- One-sided swelling: a single leg that becomes noticeably larger, warmer, or redder than the other, especially more than a few days after surgery, suggests a possible blood clot.
- Severe calf pain: pain in the lower leg that is escalating rather than improving in the first 24 to 48 hours, particularly if the calf feels hard or tight, raises concern for compartment syndrome.
- Foot drop: inability to lift the front of the foot when walking, which indicates a more significant nerve injury that may benefit from early physical therapy or bracing.
- Chest symptoms: sudden shortness of breath, chest pain, or a rapid heartbeat alongside leg pain could mean a clot has traveled to the lungs.
Milder symptoms like thigh numbness, a pins-and-needles feeling, or general achiness in the legs are common in the first few days and often resolve on their own. But even mild symptoms deserve a mention at your follow-up appointment so they can be documented and tracked.
How Surgical Approach Affects Your Risk
The type of hysterectomy you have shapes which leg problems are most likely. Abdominal hysterectomy carries the highest risk of femoral nerve compression from retractors and has roughly double the blood-clot risk compared with non-abdominal approaches.7PubMed Central. Risk Factors for Venous Thromboembolism After Hysterectomy Vaginal and laparoscopic hysterectomies avoid the large retractors but introduce lithotomy-position risks, including obturator and peroneal nerve strain and, in rare cases during long procedures, compartment syndrome. Robotic-assisted hysterectomy often involves a steep head-down tilt for extended periods, which brings its own set of positioning concerns including the patient sliding on the table and compression of nerves at the shoulder and hip.
There is no approach that eliminates all risk. What changes is the specific flavor of risk and its probability. The trend in gynecologic surgery has been toward minimally invasive methods, which generally carry lower overall complication rates and faster recovery. But even a straightforward laparoscopic case can produce leg symptoms if positioning is suboptimal or the operation runs longer than expected. The best protection is a surgical team that is aware of these risks and takes active steps to mitigate them during the procedure.
