Pinned 1 cc of NPP today in my delt like I always do and holy friggen shit it hurt like hell, felt like someone poured lava into my delt going down my arm.
I haven't felt pain like that ever from a pin. Any idea what caused it?
What part of your delt? Rear delt has alot of nerves in it. I pinned some winny in my rear delt and i could barely move my arm for 3 days and the pain was instant which anywjere else it doesnt hurt until the next day.
