recently ive been experiencing a pain in my left teste. it has only happened about three times and only happens for maybe a few hours at the longest. (this over the course of the past 7 days) the pain is relatively mild, its kind of just an annoying pain and makes me sit in uncomfortable ways, etc. should i be worried? what could this pain mean? my friend told me it could be from vasoconstriction, is there any truth to that? i am currently prescribed adderall and it has occured only when i am on the drug. thanks for any input.
