Had ring worm on scalp as a kid. Left a bald spot top corner of head. Mole on spot was brown now pink. Hurts to touch and sometimes shooting pain.

Skin findings. It is very hard to diagnose skin lesions over the telephone. If tender you might have an infection. start with seeing your primary doctor and if needed, a dermatologist. Be prepared to say how long the problem has been there, any medications and other symptoms. This needs to be seen in person.
