here are the things i have noticed so far that are painful, or uncomfortable
sore throat, it doesnt hurt at all really, just a little scratchy
sore muscles, a few weeks on T and my whole body was sore, but i liked it cause it meant i was growing a bit
boxers clinging to new growing junk, doesnt hurt, just a mild annoyance
a few times while yawning i got a charlie horse in my jaw, now that was bad, the worst pain of all of the things listed above
i think thats about it..
