i recently got some eq 500 that usually leaves a bit of a welt, but i've got a place on the back of my tricep at the injection site that's about the size of a golf ball and has been for a few days. it doesn't hurt anymore, but it feels like a big old puss ball inn there. i'm thing about sticking an 18g needle and there and seeing if i can draw some shit out if it doesn't go away. anybody else have this? possibly an abcess?
