I have injection 3cc's of test cyp in my delt and it didnt hurt that day or for the next two days really but then when i tried doing squats and the bar was on the back of my shoulders it started hurting real bad and there is a red mark about the size of a baseball around the injection site and it hurts to lift my arm up from the side. Not really swollen too bad but the skin around the area is real tight and I did feel a little hot for a couple of days but nothing real serious. its been about 5 days now. what do you think is goin on
any input is appreciated
