I have this on my arm what I assumed was from a bite that I had messed around with. I went to doctors they put me on Antibotics as it got infected as I used after bite which has amonia in it anyway it went down and almost went but didn’t. Our GP has a dermy doctor and he saw me and said looks like an over reaction under the skin but will refer to dermatologist he said it could take months to go.
i saw the dermatologist today she looked at it and said it still looked inflamed and little lumpy so she said she’d do a biopsy. I said ok, she was filling in and said she’s put suspected skin cancer but she doesn’t think thats what it is but I’m paranoid now why has she put that if she doesn’t think it?
first photo is now second is how it was after I messed with it. It’s will itchy too every so often.
