Small Bald Spot

I have recently discovered a small bald spot (the size of a pencil eraser) on the back of my head.  It started with a large, sore bump.  The bump has gone away, but the bald spot remains.  Any idea what this could be?

Hello,
This bald spot can be due to pilar cyst or due to tinea capitis. Tinea capitis is contagious and can spread direct contact with someone who has the condition, or if you touch contaminated items such as combs, hats, clothing, or similar surfaces. Diagnosis is by clinical examination of the scalp as well as a skin lesion biopsy with microscopic examination.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
