Most people who go through Mohs surgery describe the experience as far less painful than they expected. The procedure is done under local anesthesia, so you are awake but numb, and studies consistently show that average pain scores during the operation fall in the mild range. Afterward, discomfort peaks on the day of surgery and drops off quickly, with most patients reporting no pain at all by the end of the first week. That said, several factors can shift your experience up or down the pain scale, and knowing what those factors are makes the whole process easier to handle.
What the Procedure Actually Feels Like
The single most uncomfortable moment for the majority of Mohs patients is the injection of local anesthetic, usually lidocaine. A multicenter study that tracked pain during each stage of the procedure found that the average pain rating at the time of injection hovered around 2.5 on a 0-to-10 scale, which falls in the mild range. Roughly 40 percent of patients rated the injection pain as moderate, and about 10 percent called it severe.1PubMed. Pain of local anesthetic injection of lidocaine during subsequent stages of Mohs micrographic surgery: A multicenter prospective cohort study If you have ever had dental work with a numbing shot, the sensation is broadly comparable: a quick sting and burning that fades within seconds as the anesthetic kicks in.
Once the area is numb, the actual cutting and tissue removal are typically painless. Mohs surgery works in rounds: the surgeon removes a thin layer of tissue, maps its edges under a microscope, and returns to remove more only if cancer cells are still present at the margins. A common worry is that later stages will hurt more, either because the anesthesia wears off or because the wound is larger. The same multicenter study found that pain scores stayed essentially flat across five successive stages, with no statistically significant increase.1PubMed. Pain of local anesthetic injection of lidocaine during subsequent stages of Mohs micrographic surgery: A multicenter prospective cohort study The surgeon re-injects before each new layer, so numbness is maintained throughout.
The concentration of lidocaine matters less than you might think. A randomized trial comparing a standard-strength solution to one at half the lidocaine dose found equivalent pain control, as measured by both patient-reported scores and the amount of rescue anesthetic needed.2PubMed. A randomized, double-blind comparison of the total dose of 1.0% lidocaine with 1:100,000 epinephrine versus 0.5% lidocaine with 1:200,000 epinephrine required for effective local anesthesia during Mohs micrographic surgery for skin cancers Surgeons sometimes use longer-acting agents like bupivacaine toward the end of the procedure so that pain relief extends into the early recovery hours, and research shows this approach lowers pain scores during the first eight hours after surgery compared to lidocaine alone.3Dermatologic Surgery.

The First Few Days After Surgery
The local anesthetic wears off within a few hours of leaving the clinic, and that is when you will first feel the surgical site. A prospective study tracking daily pain scores found that discomfort was highest on day zero, the day of surgery, with an average score just under 2 on a 0-to-10 scale. By the next morning, scores had already dropped. By day seven, only about 16 percent of patients reported any pain at all, and those who did rated it very low.4PubMed. Assessment of postoperative pain after Mohs micrographic surgery
Another prospective cohort of over 400 patients confirmed the same trajectory: pain peaked on the day of surgery and declined steadily until roughly postoperative day four. About half of those patients took some form of pain medication on day one, but that proportion fell with each subsequent day.5Journal of the American Academy of Dermatology. Pain characteristics and analgesia in patients undergoing Mohs micrographic surgery: A prospective cohort study The overall picture is reassuring: for the average patient, meaningful discomfort lasts a couple of days, and what lingers after that is usually mild enough to ignore.
A multicenter safety study that included nearly 1,700 cases reported the average peak postoperative pain as about 2 on a 10-point scale, reinforcing the pattern that most patients’ worst moment still lands in the mild zone.6PubMed. The safety of Mohs surgery: a prospective multicenter cohort study
What Makes Some Procedures Hurt More
Not everyone has the same experience, and a few variables reliably predict whether you will land on the lower or higher end of the pain spectrum.
Where the cancer is located on your body matters. A prospective study found that the site of the skin lesion, the type of repair used to close the wound, and the number of stages all significantly predicted postoperative pain levels.7Dermatologic Surgery. Evaluation of Pain After Mohs Micrographic Surgery: A Prospective Study Areas with thinner skin and denser nerve networks, like the nose, lips, and ears, tend to generate more discomfort than, say, the forehead or cheek.
How the wound is closed plays a big role, too. Flap repairs, where nearby skin is shifted to cover the defect, are associated with the highest mean pain scores compared to simpler closure methods or grafts.8Journal of the American Academy of Dermatology. Pain after Mohs micrographic surgery: Prospective study of 433 patients Flaps involve more extensive tissue manipulation, suturing under tension, and sometimes undermining of the surrounding skin, all of which can increase postoperative soreness. On the ear specifically, patients who had a skin graft placed reported significantly more pain during the first three days than those whose wounds were left to heal on their own: the average peak score was about 3.6 for grafts versus under 1 for open healing.9Dermatologic Surgery. Assessment of Pain, Healing Time, and Postoperative Complications in the Healing of Auricular Defects After Secondary Intent Healing Versus Split Thickness Skin Graft Placement
Age is another factor. Patients younger than 66 reported higher pain scores on average. The same study found no significant difference based on sex or the final size of the wound, which surprises people who assume bigger defects automatically mean more pain.8Journal of the American Academy of Dermatology. Pain after Mohs micrographic surgery: Prospective study of 433 patients
Over-the-Counter Pain Relief Usually Does the Job
If you are worried you will need strong painkillers afterward, the evidence is encouraging. A randomized trial compared three regimens head to head: acetaminophen alone, acetaminophen with ibuprofen, and acetaminophen with codeine. The combination of acetaminophen and ibuprofen consistently produced the lowest pain scores at every measured time point and had fewer side effects than the codeine group.10PubMed. A randomized controlled trial comparing acetaminophen, acetaminophen and ibuprofen, and acetaminophen and codeine for postoperative pain relief after Mohs surgery and cutaneous reconstruction In other words, over-the-counter medications outperformed the prescription opioid, while causing less nausea and constipation.
Current dermatology guidelines reflect this. Ibuprofen or acetaminophen, used alone or together, are now recommended as the first choice for pain relief after skin surgery, with opioids reserved for unusual circumstances.11Journal of Dermatology for Physician Assistants. Ibuprofen is a Safe and Effective Alternative to Opioid Analgesics in Dermatologic Surgery The practical advice most surgeons give is to take acetaminophen and ibuprofen on a schedule for the first 24 to 48 hours, rather than waiting until pain builds up, so the medications stay ahead of the discomfort.
Opioid prescribing after Mohs surgery has changed dramatically. A claims database analysis covering more than 350,000 Mohs patients found that the percentage filling an opioid prescription peaked near 40 percent in 2011 and fell to under 12 percent by 2020.12PubMed Central. Rates of Opioid Prescriptions Obtained After Mohs Surgery: A Claims Database Analysis From 2009 to 2020 A more recent single-institution retrospective study reported that only about 13 percent of patients received an opioid prescription after their procedure.13Journal of Drugs in Dermatology. Opioid Prescriptions and Pain-Related Patient-Initiated Communication After Mohs Micrographic Surgery: A Retrospective Cohort Study Among those who do take pain medications, acetaminophen is by far the most common choice, used by about three-quarters of patients who reach for anything at all.14JAMA Dermatology. Opioid Pain Medication Use After Dermatologic Surgery: A Prospective Observational Study of 212 Dermatologic Surgery Patients
One caveat: if your surgeon tells you to avoid ibuprofen or other anti-inflammatory drugs because of bleeding risk or another medical reason, follow that instruction. Acetaminophen alone still provides meaningful relief and does not affect blood clotting.
How Anxiety Changes the Pain You Feel
Your mental state going into surgery has a measurable effect on how much pain you report afterward. A study using two validated anxiety scales found that while most Mohs patients experienced little postoperative pain overall, those with high anxiety about pain reported significantly greater discomfort.15PubMed. Prediction of postoperative pain after Mohs micrographic surgery with 2 validated pain anxiety scales This is not imaginary pain. Anxiety lowers pain thresholds through well-established neurological pathways: stress hormones sensitize nerve endings, and the brain’s threat-detection systems amplify incoming pain signals when they are expected.
The practical takeaway is that anything you do to lower your anxiety before the day of surgery will likely reduce the pain you feel. A review of preoperative anxiety interventions in dermatologic surgery found that educational content explaining what will happen during the procedure, whether delivered through a phone call, a video, or a visual walkthrough, can reduce patient anxiety.16PubMed. A practical guide to reducing preoperative and intraoperative patient anxiety in dermatologic surgery If your surgeon’s office offers a pre-procedure call or informational packet, engage with it rather than skipping it. Knowing the sequence of events, how long the waiting periods between stages tend to be, and what the wound will look like removes the element of surprise that feeds anxiety.
On the day itself, bring something to occupy the waiting periods. Each stage involves a gap of 30 to 60 minutes while the tissue is processed and examined under the microscope. Sitting in a clinic room scrolling through worst-case scenarios on your phone is the least helpful thing you can do for your pain levels. A book, a podcast, or a companion to talk with serves you better.
Complications That Could Affect Pain
Mohs surgery has a remarkably low complication rate, but complications that do arise tend to involve increased pain as their first symptom. In a prospective study of over 1,300 cases, only four complications (about 0.3 percent) occurred on the day of surgery: one episode of bleeding and three hematomas. Eighteen additional delayed complications (about 1.3 percent) appeared in the days and weeks afterward, including graft or flap tissue loss, additional hematomas, one wound infection, and one wound separation.17JAMA Dermatology. A Prospective Evaluation of the Incidence of Complications Associated With Mohs Micrographic Surgery A separate multicenter safety study found an overall minor complication rate of about 2.6 percent, with no major complications at all.6PubMed. The safety of Mohs surgery: a prospective multicenter cohort study
The signs worth watching for include pain that suddenly gets worse after a period of improvement, swelling that appears or increases days after surgery, warmth or spreading redness around the wound, and bleeding that soaks through a pressure bandage. One scenario that catches people off guard is a delayed hematoma, a blood collection that forms not on the day of surgery but days later. This is more likely if you are taking a blood-thinning medication. A recent case series documented delayed-onset hematomas in patients on direct oral anticoagulants that were not stopped before the procedure.18PubMed Central. Delayed-Onset Hematomas Following Mohs Surgery in Patients Taking a Direct Oral Anticoagulant If you take a blood thinner, your surgeon will discuss with you whether to pause it. In many cases, the bleeding risk from continuing it is considered manageable, but you should know that delayed hematoma is a possibility and what it looks like.
Infection after Mohs surgery is uncommon. The wound care routine is straightforward: keep the area clean, apply petroleum jelly or the ointment your surgeon provides, and change the bandage as directed. Contact your surgeon’s office if pain escalates rather than improves, or if you develop a fever.
When Pain Lingers Beyond the Expected Timeline
For the vast majority of patients, meaningful pain resolves within the first week. Occasionally, though, discomfort persists or changes character in a way that suggests something beyond normal healing. Neuropathic pain, a burning, shooting, or electric-shock sensation caused by nerve damage or entrapment in scar tissue, is one rare but recognized possibility. A case report described a patient who developed persistent pain around the ear six weeks after Mohs surgery. Evaluation pointed to nerve entrapment compounded by inflammation, and the patient required a multimodal treatment approach involving more than just standard painkillers.19PubMed Central. Multimodal management of postoperative neuropathic pain and scar-associated nerve entrapment following Mohs surgery
This kind of outcome is unusual enough to be published as a case report, which tells you how rarely it comes up. But if you notice pain that is getting worse rather than better several weeks out, or pain that feels different from the initial surgical soreness, especially sharp, shooting, or triggered by light touch, bring it up with your surgeon. Neuropathic pain responds to different treatments than ordinary postoperative soreness, and catching it early tends to produce better results.
Numbness, Tightness, and Other Sensations That Are Not Pain
Pain gets all the attention, but many Mohs patients are more bothered by sensations they did not expect. Numbness around the surgical site is extremely common and can last weeks to months. Small sensory nerves are inevitably cut during the procedure, and they regenerate slowly. During the regrowth phase, you may experience tingling, itching, or brief zaps of sensation, all normal signs that nerve fibers are reconnecting.
Tightness in the skin is another frequent complaint, especially after flap closures. As the wound heals and scar tissue matures, the area can feel stiff or pull when you make facial expressions. This typically softens over several months as the collagen in the scar remodels. Gentle massage of the scar, starting a few weeks after suture removal and once your surgeon gives the green light, can help break up adhesions and speed this process.
Itching during healing is almost universal and can sometimes be more annoying than any pain you experienced. It usually signals healthy granulation tissue forming and is not cause for concern unless accompanied by redness, warmth, or discharge that suggests infection or a reaction to wound care products. One trial comparing wound dressings found that contact dermatitis occurred in about 16 percent of patients using a topical triple antibiotic ointment and in none of those using an antibiotic-free wound dressing.20Journal of the European Academy of Dermatology and Venereology. Comparing the use of a novel antibiotic-free film-forming topical wound dressing versus a topical triple antibiotic in dermatologic surgical procedures including Mohs micrographic surgery If itching is intense and localized to the wound margins, a reaction to your ointment is worth considering. Switching to plain petroleum jelly often resolves it.
Practical Tips for the Day of Surgery
A few things that veterans of Mohs surgery wish they had known going in:
- Eat beforehand: The procedure can take several hours when multiple stages are needed. Having food in your stomach helps you tolerate the lidocaine (which can cause lightheadedness in some people) and keeps your energy up during the waiting periods.
- Dress comfortably: You will be lying on a procedure table and then sitting in a waiting area, potentially for much of the day. Button-up shirts are preferable if your surgery is on the face or neck so you do not have to pull anything over a fresh bandage.
- Start pain medication early: Your surgeon will likely suggest taking acetaminophen or ibuprofen before the local anesthetic fully wears off, rather than waiting until you feel pain. Staying ahead of the discomfort is easier than chasing it.
- Plan to rest that evening: Elevating the surgical area, especially if it is on your face, and avoiding bending over or heavy lifting reduces swelling and bleeding risk. Most people feel well enough to resume normal activity within a day or two, but the first evening is best spent being boring.
Avoid alcohol for at least 24 hours after surgery, and longer if your surgeon advises it. Alcohol dilates blood vessels and increases bleeding risk at the surgical site. The combination of alcohol and acetaminophen also stresses the liver, so separating the two is good practice regardless of surgery.
