ok, i am running sust/deca in my cycle right now. i normally rotate my injection spots....but on mon i shot deca/sus....then wed....deca/sus....then fri just sust. i shot the half cc of sust real close to where i shot the deca/sus on mon. it has become really swollen...about the size of a golf ball or a little smaller, its red just around the area but there's a tiny bit of swelling around the red spot. its warm just a little, not much of a difference from my other glute. i DONT have a fever or feel bad. what should i do??? is it in infection??? im thinking it may not be due to the fact that i did not rub it when i shot my last sust. any advice? thx
