when im pitching, my arm is always fine out on the mound. but when i get in the dugout and put on a jacket it kills. then once i throw another pitch its fine till i sit for 30 seconds or more.
somethin called adrenelin my friend
something called that isn’t a good thing :
edit: the pain, not the adrenaline
nvm, i think i found my problem. im not striding far enough. im 6ft and was only striding like 5’. in the 4th inning yesterday i started taking a longer stride and my pain was gone.
