I have a small lump on the inside of my right leg, just above the knee.  It is not red. It is hard. It is sometimes painful....burning....and othertimes it doesnt hurt at all.  I was wondering if it could be a parasite under the skin living in my tissue....or is it just a cyst?
Hi. Since how long have you got this ? This is the most unusual site for parasite. There is more chance of this being a cyst or lipoma or neuroma. I would advise such a patient to consult the Surgeon and get this excised. The excision helps in two ways : First, one gets the disease out of the body. Secondly, you get a histopathological diagnosis to confirm what it been.
