Painful Brown Spot — Should I Worry?
Quick answer
Yes — get a brown spot that hurts checked promptly. Noticing pain in a pigmented mark often causes immediate concern, yet most painful skin lesions are actually related to benign inflammation or minor localized infections. A common culprit is a ruptured cyst or an irritated seborrheic keratosis rather than a life-threatening condition. While the presence of discomfort is usually a sign that your immune system is responding to a surface-level injury or blocked pore, it is not a symptom to ignore. In many cases, the discomfort will subside within a few days as the inflammation or injury heals. You should shift your assessment from simple monitoring to seeking an urgent professional opinion if the pain is accompanied by rapid expansion, persistent bleeding without a known injury, or if the mark begins to look significantly different from any others on your body. Early evaluation ensures that serious issues like melanoma are ruled out promptly and effectively. Next step: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).

What to look for
Visible changes in the architecture of the lesion can provide important clues about whether you need a clinical exam. Pay close attention to any asymmetry where one half of the mark fails to mirror the other in shape or density. You should also watch for a blurring of the outer edges where the pigment seems to spill out into the surrounding healthy skin. The presence of multiple colors, such as a mix of black, blue, and tan within the same area, is another significant warning sign to note. Beyond just color, feel the texture of the spot to see if it has become noticeably harder than the skin around it or if the surface has developed a persistent crust or open sore. These physical shifts are often more indicative of risk than the presence of pain alone and require a prompt dermatological consultation to ensure safety and peace of mind.
Most likely causes
Seborrhoeic keratosis
Waxy, "stuck-on" benign growth — very common after age 40.
Solar lentigo (sun spot)
Flat brown patch from cumulative UV — usually harmless.
Melanoma
Skin cancer that often presents as a new or changing brown/black spot with irregular borders.
Café-au-lait macule
Uniform light brown patch present from childhood.
Red flags — get reviewed
- •Asymmetric shape or irregular borders (ABCDE)
- •More than one colour within the spot
- •Diameter greater than 6 mm or growing
- •New itch, bleeding or change in any existing brown spot
What you can do while you decide
- ✓Photograph monthly with a coin or ruler for scale
- ✓Use SPF 30+ daily and avoid further tanning
- ✓Avoid DIY removal — it destroys the diagnostic features a dermatologist needs

The safest next step is: seek same-week medical review (same day if also bleeding heavily, spreading or with fever).
Key red flags include: Asymmetric shape or irregular borders (ABCDE); More than one colour within the spot; Diameter greater than 6 mm or growing; New itch, bleeding or change in any existing brown spot. Any of these alone is reason to book a dermatology assessment promptly.
The most common causes are Seborrhoeic keratosis, Solar lentigo (sun spot), Melanoma, Café-au-lait macule. 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.
