So what has been happening.... last couple of cycles, directly after injection (with in 30 mins, sometimes instantly) I feel pressure center- right side'ish in my chest, where my heart is. It only happens directly after an injection of testosterone. It doesn't hurt, but it does feel weird. I usually feel it for a day or two and the more I think about it the worse it is. I don't feel it when I am at the gym, doing cardio, lifting etc. only when I am relaxing. I did go to the doc. Had all my blood work ran, had an EKG and a chest X-ray. The doctors are certain it is not my heart, I am not so sure. My blood work was normal, so was everything else. I haven't felt it for about a month but today after a shot boom it's back. I am not sure if I am tripping myself out or if I am legitimately having a heart issue. The doc seems to think its anxiety or a pulled chest muscle. I am 33, got about 6 cycles under my belt and I am other wise healthy. 6'1" 225 16%. I eat clean and have never had a heart problem. Anyone have any ideas? Thanks dudes
