Hi I wasn't rele sure on where to post this as to get the best answer. But I took my first testosterone c shot 1cc 250mg and I did it in my shoulder and it's been hurting for days now. Not like aggravating serious pain. But annoying pressure pain. My buddy started the same day he isn't rele experiencing the same problem. Do I have an infection or is it just Virginia muscle. It does feel a tiny bit hot but I could be overthinking any help please ?
