Ok, i posted here earlier and i need some advice. i injected some winstrol zambon into my shoulder and it was like the 8th shot into the same spot. I know I fu**** up but now I have a Knot. I need to know if this is serious and if with massage it will pass. Or if anyone can tell me what to do. I'm really starting to worry and I have no idea what to do. I'm starting to go on a bad one. Can someone give me some good advice. Thank you..
