Question. I'm in week 4 of test E cycle. I haven't had any issues with the gear until now. I would think if it was just dirty it would've done this before now. I pinned my right shoulder this past Monday. Everything was fine all week. Even pinned my left shoulder Thursday. Starting Friday (4 days after pin) my right shoulder felt sore when I woke up. It felt like someone had punched me in the arm but no bruise. No redness or swelling. Saturday it was a little more sore than this morning (Sunday) it's a little more sore than the day before and the area that is sore is a little larger. Little to no redness but it's pretty hard and slightly swollen. I don't have access to a thermometer right now but I feel ok. I understand if it is an infection I will need to take an antibiotic. What antibiotic should I purchase? Which one would the dr most likely prescribe?
