So Idk if its a rash or what to really call it, but in the past week or so I've developed a few different skin issues and now im starting to think they are all related. idk if it has anything to do with my gear use but I'm on mast and test and I've had almost no acne issues with gear, besides a small number of black heads and shit on shoulders and back. I have this very painful and red area on my chest, and another on the inside of my arm. they are super painful especially to the touch. They both look different, but the pain is the same, and its like something ive never felt before, its almost is like the pain from a bad burn or something. also in my armpit the skin is all raw and I've had that happen before with certain deodorant, so I figured that's what that was from, and i thought maybe the chest was a bunch of ingrown hairs but I think thats highly unlikely because of how large the area is. but now that i have all three going on idk what it is. anyone recognize these things and know what it could be? Also none of my gear use has changed in over a month and this started like a week ago at most, and I can't really think of anything that's changed at all, that could effect this.
