Pain in knee after injection???

whats up bro's, my buddy injected 1cc of qv eth 250 in my glutes(right side) two days ago. The day i took the shot i wasn't painful at all, but these next days my ass is not too sore, but i feel pain in my right knee?? wtf?? what could that be from. I cant even walk up the stairs, i feel a sharp pain in it. any feedback i apprecieate guys

I honestly don't think it's the injection at all, a pain in your knee is probally associated with training...

you should be fine. i cant think of a reason your knee would hurt from shooting the glutes.
