Thank you for your help. I saw my family provider today because they said they could take care of the problem when I called for a dermatology referral. They prescribed 500 mg of Cephalexin Monohydrate, an antibiotic. Tonight after a long hot shower I parted my hair to look at it and some puss came out so I am thinking that is OK. No one said anything about having the cyst removed, I hope it does not cause me any more problems and at least no serious ones. I feel much better about it now though. Thank you again!
Hello,
It can be either a boil or an infected sebaceous cyst. They may occur anywhere on body but scalp, ears, back, face, and upper arm, are common sites for sebaceous cysts. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause such cysts.
Generally no treatment is required but they become painful then it means they are infected, then surgical excision by traditional wide excision, minimal excision, and punch biopsy excision may be required. My sincere advice is to consult a dermatologist.
I hope it helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
