For the first time ever i injected testoprim-d(50mg prop/200mg e) yesterday and now i have a small red lump, that is warm to the touch, is it usually warm the first day after? Should i get some antibiotics right now, if so, does amoxicillin work? its not so much that sore in my ass where i can't sit down or move around, but it does bother a bit. The shit is mexican and i heard its infection prone, any immidiate input would be greatly beneficial, thanks.
