A week ago, I stupidly injected way too much test prop in my ass cheek. I was in so much pain and I started getting flu like symptoms and was EXTREMELY tired. After the third day, the symptoms were gone but I noticed a rather large lump in the upper/inner part of that same ass cheek...near the lower back. I went to the hospital and they said it was POSSIBLE I had some sort of staph infection. So they put me on Bactrim and I am on my 4th day of taking it. I am no longer sick and the lump KIND OF went down just a little...but it is still there. It's freaking me out. Do you guys think this is a pretty bad staph infection or u think because I injected so much Test Prop, it's just buildup (even though it's not close to the injection site)? It's painful to touch as well.
