Strange lump Appeared on buttocks last month, initially thought a heat boil & used Pain refile patch until last week. Thought it got all healed up, so I stopped using the patch but now the lump is back. Here I attached a photo of the lump
I'm not capable of viewing images, but based on your description, I strongly recommend consulting a doctor or dermatologist to examine the lump and determine the cause, as it could be a sign of an underlying condition, such as a cyst, abscess, or skin infection.
