i injected into my left thigh. But it went wrong cos i hit a vain twice and i aspirated so i just took out the needle and replaced it with a new one. I finally had it right but i did flex my muscle thigh on accident because i was in a very uncomfortable position. Now 1 day later its extremely swollen and a bit red on the injection site it doesn,t hurt when i press against or anything but when i sit still for a few hours i have a bit trouble walking on the leg the first couple of minutes. Because it hurts. i,m a bit worried because its so swollen my left thigh is about twice the size it used to be. What do you guys think ?
