I put a cc of test in each of my shoulders today and the left side swelled very quickly. Ive done this plenty of times and this is my first encounter with this. It dosnt really hurt, no more sore than usual but the swelling is kinda bad. The needles my stupid friend have were for insulin and were very small and my left shoulder bleed a decent amount when i pulled it out. Could i have pushed it in to fast or maybe not gone deep enough with the little needle? I guess im really just seeing if i should be concerned. This is my third cycle and thid is my first problem.
