Painful Mole — Should I Worry?
Quick answer
Yes — get a mole that hurts checked promptly. Experiencing discomfort in a skin spot can be startling, but the majority of sore lesions turn out to be harmless irritations rather than anything life-threatening. Often, a bump that hurts is simply reacting to friction from clothing, a minor bacterial infection in a hair follicle underneath, or a small cyst that has become inflamed. While most cases do not lead to a serious diagnosis, pain can occasionally be a signal that cells are changing rapidly. If the tenderness is accompanied by a persistent open sore that refuses to heal or if the spot feels like it is growing significantly deeper into the skin rather than just sitting on top, the situation shifts from routine monitoring to requiring a professional evaluation. You should remain calm but check for physical changes that suggest the lesion is more than a simple skin rub. Next step: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).

What to look for
Watch closely for specific visual clues that distinguish a common blemish from something more concerning like melanoma. Pay attention if the edges of the mark become blurred or ragged, looking more like a map than a clean circle. You should also note if the color is no longer uniform, especially if shades of black, blue, or stark white appear mixed together. Another red flag is a change in the texture of the surface, such as the skin becoming scaly, crusty, or starting to ooze fluid without being picked at first. Significant asymmetry, where one half of the spot looks entirely different from the other half in shape or thickness, is a key sign to bring to a doctor. These physical shifts are often more telling than the sensation of pain itself when determining the risk of cancer.
Most likely causes
Common mole (naevus)
Symmetrical, uniformly coloured, stable over years.
Atypical (dysplastic) mole
Larger or irregular mole — higher melanoma risk but usually benign.
Melanoma
Skin cancer that may arise in an existing mole or as a brand new spot.
Congenital naevus
Mole present from birth — most are harmless but warrant monitoring.

The safest next step is: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).
Key red flags include: ABCDE: Asymmetry, Border irregularity, Colour variation, Diameter >6 mm, Evolution; Itching, bleeding or crusting in a previously stable mole; The "ugly duckling" — a mole that looks different from your others; New mole appearing after age 40. Any of these alone is reason to book a dermatology assessment promptly.
The most common causes are Common mole (naevus), Atypical (dysplastic) mole, Melanoma, Congenital naevus. Most are benign, but pain often points to inflammation, infection or pressure on a nerve, but tenderness in a slowly-growing skin lesion can also signal squamous cell carcinoma.
Seek same-week medical review (same day if also bleeding heavily, spreading or with fever). Seek same-day care for: heavy bleeding, rapidly spreading redness with fever, severe pain, or a new black streak under a fingernail or toenail.
