alright ive been on my current cycle for 5 weeks now and i did a delt injection of 250mg of test e....and there is a slight swelling in my arm not in the injection area but in the middle of my bicept and tri, this happened last time injection was administered in that delt but went away after a few days but its bigger this time, no pain a slight soreness and a very slight redness, basically it feels like somone decked me in the arm without the bruise and pain. could this be caused by hittting a nerve, is this something i should have checked by a doctor or let it pass and see?
