Persistent pain at a melanoma excision site, even years after surgery, is a well-documented phenomenon that affects roughly one in ten patients. The cause is almost always related to the surgery itself rather than the cancer coming back. Nerve injury during the original procedure, scar tissue restricting underlying tissues, and changes in how your nervous system processes pain signals can all keep the area tender or uncomfortable long after the wound has healed. That said, new or changing pain at an old surgical site deserves medical attention, because ruling out recurrence is part of responsible follow-up.
How Common Is Lasting Pain After Melanoma Removal
Chronic post-surgical pain, defined as pain persisting beyond the normal healing window, is more common after melanoma excisions than most people expect. In a study of over 350 melanoma patients, about 10% reported pain in the scar area within the past month, and roughly 9% met criteria for chronic pain. Most described it as mild with little effect on daily activities, but a small subset reported moderate to severe pain that meaningfully interfered with their lives.1PubMed. Persistent pain after surgery for cutaneous melanoma A separate multicentre study found that about a third of patients reported pain at their surgical site, and a small percentage scored as high risk for nerve-related pain. The researchers noted that this pain did not seem to improve with time, making it a chronic concern rather than something that fades on its own.2PubMed.

One detail that stands out in the research is that younger age at the time of surgery tends to predict a higher risk of persistent pain. That finding may seem counterintuitive, since younger tissue generally heals faster, but it could reflect differences in pain reporting, activity levels placing more demand on the surgical site, or a longer expected follow-up period in which pain has time to become established.1PubMed.

Nerve Damage During Surgery
The single biggest driver of lasting pain at a melanoma excision site is injury to small sensory nerves during the procedure. Melanoma removal typically requires a wide local excision, meaning the surgeon cuts a margin of healthy-looking skin around the tumor. That margin slices through the fine network of cutaneous nerves running through the skin and the tissue just beneath it. When those nerves are cut, crushed, or stretched, they can regenerate abnormally, sending pain signals even when nothing harmful is happening at the site.
This type of pain is called neuropathic pain, and it has a distinctive character. People describe it as burning, shooting, tingling, or an electric-shock sensation rather than a dull ache. Sensory changes in the surrounding skin are a strong marker. In the same large study mentioned earlier, about a third of patients reported altered sensation such as numbness, tingling, or hypersensitivity. Among those with sensory changes, a full quarter also had pain, compared to only 3% of patients whose sensation was normal.1PubMed. Persistent pain after surgery for cutaneous melanoma In other words, abnormal sensation and chronic pain go hand in hand at these sites, and the nerve injury driving both problems can persist indefinitely.
Pain After Lymph Node Surgery
If your melanoma treatment involved removing lymph nodes, the risk of long-term pain increases substantially. There are two common lymph node procedures in melanoma care: a sentinel lymph node biopsy, which removes just one or a few nodes to check for cancer spread, and a complete lymph node dissection, which removes an entire group of nodes. The dissection is more invasive and has a much higher rate of lasting complications.
Research comparing the two procedures found that altered sensation and pain were far more frequent after a full dissection. About 82% of dissection patients reported changed sensation, and 34% had persistent pain, versus 32% and 14% for biopsy patients. Among those who had the full dissection, roughly 12% described at least moderate pain, and 14% said the pain affected their quality of life. Clinical evaluation of these patients showed that nerve injury was the main underlying mechanism: the vast majority met criteria for neuropathic pain based on standardized assessments.3PubMed. Persistent pain after lymph node excision in patients with malignant melanoma is neuropathic
A prospective study that tracked patients over time found a similar pattern. Ten days after a sentinel biopsy alone, about a third of patients had some pain, but by six months none of those patients reported any. In contrast, patients who had both a sentinel biopsy and a complete dissection had a much harder course: more than half still had pain at six months, with one patient scoring a 70 out of 100 on a pain scale. Altered sensation and numbness were common in both groups at the six-month mark, but the combined-surgery group was hit hardest.4PubMed Central. Natural history of pain associated with melanoma surgery These findings make it clear that the more extensive the lymph node surgery, the greater the odds of pain that lingers for years.
Scar Tissue and What It Does Below the Surface
Even when nerves heal properly, the scar itself can be a source of ongoing discomfort. Scar tissue is structurally different from the skin and connective tissue it replaces. It is stiffer, less elastic, and does not slide smoothly over the layers beneath it the way normal tissue does. When a scar tethers to the underlying fascia, the connective tissue sheet that wraps around muscles and organs, it can restrict normal movement. That restriction generates abnormal tension that radiates outward, sometimes producing pain in areas that seem unrelated to the original wound.5Pain Management – Practices, Novel Therapies and Bioactives. Clinical Insights into the Importance of Scars and Scar Release in Paediatric Chronic Myofascial Pain
This explains why some people feel tightness, pulling, or aching at the excision site years later, especially when they stretch, exercise, or even change posture. The discomfort is mechanical in nature, driven by the scar’s inability to move with the surrounding tissue. It can be particularly noticeable at sites where the skin is thin and close to bone or joints, such as the shin, scalp, or near the shoulder blade. If your melanoma was removed from an area like this, the biomechanical effects of the scar are a plausible source of lasting discomfort even without nerve involvement.
When Your Nervous System Turns Up the Volume
Sometimes the problem is not at the surgical site at all but in how your central nervous system is processing signals from that area. A phenomenon called central sensitization can develop after surgery or nerve injury, in which the spinal cord and brain become overly responsive to normal sensory input from the affected region. Signals that should register as light touch, mild pressure, or a slight temperature change get amplified and interpreted as pain.
Central sensitization shows up as exaggerated pain responses: the area around the scar may be painful when lightly brushed, pressure that would not bother you elsewhere feels sharp, and the pain can linger after a stimulus is removed. This is not imagined pain. It reflects a measurable change in the excitability of neurons in the pain-processing pathways. Researchers have documented central sensitization as a contributing factor in a wide range of chronic pain conditions, including post-surgical pain specifically.6PubMed Central. Central sensitization: implications for the diagnosis and treatment of pain The good news is that central sensitization is considered reversible, at least in principle, though it can take time and targeted treatment to dial it back down.
Fear of Recurrence and Pain Perception
A dimension that does not get enough attention is the psychological link between cancer survivorship and pain. If you have had melanoma, any new sensation near the old site can trigger a very specific fear: is the cancer back? That fear is not irrational. Melanoma can recur locally, and the site of the original excision is one place it can show up. But the fear itself can change how your brain processes pain signals from that area.
Research in cancer survivors has identified a pattern where pain acts as a conditioned fear stimulus. Because pain was originally associated with a life-threatening diagnosis, some survivors become hypervigilant toward any physical sensation near the old site. That heightened attention makes pain feel more intense and more alarming, which in turn drives more attention to the area, creating a self-reinforcing cycle of perceived pain and fear of recurrence.7PubMed Central. Fear of cancer recurrence and perceived pain in patients with breast cancer: A network analysis approach This does not mean the pain is “all in your head.” It means that real signals from scar tissue or nerve endings are being amplified by a brain that has learned to treat those signals as high-priority threats. Addressing the fear component through cognitive behavioral therapy or discussions with your oncologist can genuinely reduce the pain experience.
Could the Pain Mean the Melanoma Is Back
This is the question most people are really asking, and it deserves a straightforward answer. Local recurrence at the site of a melanoma excision is possible but uncommon when adequate surgical margins were achieved. Pain alone, without a visible lump, new pigmentation, or change in the scar’s appearance, is not a typical sign of recurrence. Melanoma recurrences tend to present as visible or palpable nodules rather than as isolated pain.
That said, clinicians take new symptoms at old excision sites seriously. Specialized ultrasound techniques can now evaluate melanoma scars for clinically hidden recurrence. In one approach, scars are classified by their appearance and blood-vessel patterns into benign, indeterminate, or suspicious categories. Suspicious findings get biopsied, indeterminate ones get closer monitoring, and benign-appearing scars continue routine follow-up.8PubMed Central. Ultra-High-Frequency Ultrasound of Melanoma Excision Scars for Detection of Clinically Occult Local Recurrence: A Single-Center Retrospective Study If you have new or worsening pain at your melanoma scar, bring it up with your dermatologist or oncologist. They can examine the site, image it if needed, and put your mind at ease or catch a problem early. But the statistical reality is that the pain is far more likely to be surgical in origin than cancer-related.
Treatment Options for Painful Melanoma Scars
If your scar pain has been lingering for years, you are not stuck with it. A range of treatments exists, and most clinicians will start with the least invasive options. Topical medications are a common first step, particularly lidocaine patches or creams that numb the area, and capsaicin cream, which works by desensitizing pain receptors in the skin over time. Other systemic options used for nerve-related pain include certain antidepressants and anti-seizure medications that dampen overactive pain signals.9PubMed Central. Diagnosis, Treatment, and Management of Painful Scar: A Narrative Review
For pain that is primarily mechanical, from scar tissue restricting movement underneath the skin, physical therapy and scar massage can help. Techniques that mobilize the scar and break up adhesions between the scar and deeper tissue layers sometimes provide substantial relief, especially when the tightness has been causing compensatory posture changes. Injections into or around the scar, including corticosteroid injections or local anesthetic blocks, are another option when topical treatments are not enough. In stubborn cases, scar revision surgery can physically release a tethered scar, though this creates a new wound and a new healing process, so it is usually reserved for situations where the pain is significantly affecting daily life.
Pain from Radiation or Immunotherapy
Not all melanoma treatment is surgical. If you received radiation therapy to the excision site or surrounding lymph nodes, late radiation effects can contribute to pain years down the line. Radiation-induced fibrosis, a progressive scarring and stiffening of irradiated tissue, is a recognized late complication that is generally considered irreversible once established.10PubMed. Current management for late normal tissue injury: radiation-induced fibrosis and necrosis The fibrosis can compress nerves, restrict tissue movement, and produce chronic deep aching or burning in the treated area. If your melanoma was treated with adjuvant radiation and you are now experiencing pain in or near that field, radiation fibrosis is a plausible culprit.
Immune checkpoint inhibitors, which are increasingly used in advanced or high-risk melanoma, can also cause nerve-related pain as a side effect. These drugs work by unleashing the immune system against cancer cells, but that same immune activation can sometimes attack healthy nerves. Reports describe patients developing tingling, numbness, and neuropathic pain in their limbs during or after treatment.11PubMed Central. Immune-Related Peripheral Neuropathy Associated with Immune Checkpoint Inhibitors: Case Report and Review of Literature While this neuropathy is not localized to the excision site, it can affect the limb where the melanoma was removed and be mistaken for a surgical complication. Research into the underlying mechanism has found that about a third of these cases involve painful damage to the nerve fibers themselves, as opposed to the nerve’s insulating sheath.12PubMed Central. Electrophysiological findings in immune checkpoint inhibitor-related peripheral neuropathy If you received immunotherapy and are experiencing new pain or sensory changes, mention the treatment history to your doctor so they can distinguish immune-mediated nerve damage from surgical scarring.
Suture Granulomas and Foreign Body Reactions
An uncommon but real cause of delayed pain at a surgical site is a reaction to suture material left behind during the original closure. When the body encounters a foreign material it cannot fully absorb or break down, it walls it off with a lump of inflammatory tissue called a granuloma. This can happen with both absorbable and permanent sutures, sometimes decades after surgery. Case reports have documented suture granulomas appearing as painful lumps 30 years after the original operation.13PubMed Central. An Exceptional Case of Suture Granuloma 30 Years Following an Open Repair of Achilles Tendon Rupture: A Case Report
A suture granuloma typically presents as a firm, tender nodule at or near the scar line. It can be mistaken for a recurrence, which makes it especially anxiety-provoking for melanoma patients. An ultrasound or biopsy can distinguish a granuloma from something more concerning. If the granuloma is confirmed, the usual treatment is surgical removal of the offending suture material and the surrounding inflammatory tissue, which generally resolves the pain.
Skin Grafts and Donor-Site Pain
If your melanoma excision was large enough to require a skin graft or tissue flap for closure, you have two potential pain sites: where the melanoma was removed and where the graft was harvested. Donor-site wounds, particularly from split-thickness skin grafts, are frequently associated with pain and scarring that can linger well beyond the initial healing phase.14PubMed. Split-thickness skin graft donor-site morbidity: A systematic literature review Some patients find that the donor site is actually more bothersome than the melanoma excision site itself, especially if it was on a weight-bearing area like the thigh. The grafted skin at the excision site also heals differently from a primary closure, often with less sensation and a different texture, which can produce its own set of odd sensations including itching, tightness, and intermittent tenderness.
When patients describe pain “where the melanoma was removed,” it is worth clarifying whether the discomfort is at the excision site, the donor site, or both. They can have entirely different causes and respond to different treatments. The donor site is essentially a controlled burn wound and heals like one, while the excision site with its graft involves the additional variable of nerve discontinuity between the transplanted skin and the surrounding native tissue.
