my Sustanon lump
This happened to me last week.
I had lump on my ass, very swollen and painful. The worst I've ever had. My biggest fear was of course an abcess, I waited 2 days after the injection, since it was only getting worse I went to the doc...
I used my insurance and told the doc it was a B12 shot. She explained to me that an abcess/infection would not appear in such a short period of time. It would take at least 1 week. She just gave me an antibiotic and vioxx. It subsided in 5 days...
