9 times out of 10 doc will say it’s an infection even if it isn’t, i stopped pinning high dose test tren the pain is crippling, i made a few mistakes that fucked me up and scared me, i shot in triceps and hit the lymphatic system THAT was probably the worse. I tried to foam roll one to reduce pip and THAT was dumb. I mean i still have the awkward shot once in a while that i just can’t explainthe pain from like once i went ventrogluteal and couldn’t walk straight for 3 days…. Rule of thumb if it doesnt start getting better after 3 days it might be time to go visit a doc definitely could be an infection
