[|Human|] I have hard crusty lump on my head. Is there an over the counter medication that can treat this. It doesn t hurt but it is an inconvenience when combing my hair. I also seem to have small pimple-like formations on the scalp. I have had shingles in the past . Could this be a reoccurance. They do not hurt, though. I also recently contacted ringworm on my foot. I solved that problem with Lotriman. A doctor (not a dermatologist) said the bump on my head was definitely not a fungus.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some enlarged lymph node or some soft tissue tumor or skin adnexal tumor. You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
