im in my third week of testosterone enanthate cycle. running for 12 wks. i pin twice a wk, monday and friday. all my pins went smoothly...until my fourth. I pinned all in my quads, changing from right to left and so on. I took my fourth pin friday, and went to the gym later and did back & biceps. the next day later in the afternoon, i was having pain near the injection site. It feels like a big knot in there or like someone threw a fast pitch at my leg. It hurts when i bend my leg, and im positive theres no way i can go to the gym to do legs... im applying muscle rub cream on it and applying hot water too. Im getting a little nervous. What do you guys think it is??? any help is greatly appreciated guys. thanks.
