[|Human|] I have a hard lump on my head , circumference size of a dime , it has been there 5 weeks . I tried to insert needle to see if it would drain ( just a little blood ). It hurts if I push down on it . I was working three days strait when it came had lack of sleep and maybe immune system was down . What could it be?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Hard lump on your head can be Desmond cyst, lipoma or some skin adnexal tumor.  You should go for biopsy and histopathological examination of that lump.  Then you should take treatment according to diagnosis. 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. Don't forget to click, thank you.
