Someof you may have read my post about my shot last tues. My first time using sust. and today my ass hurts like none other and i swear theres a little swellingthere. It feels a little warm, but my shot was shitty and i think i may just have torn up some of the muscle. Its not red...but all i've been thinkin about the last day is the word abcess. Im hoping its mostly in my mind, what do yall think. By the way what is involved if it is an abcess?
