what you are going through is what many runners go through with shin splints.. you have 'forearm splints'
2 things can happen
1. you can keep pounding away and they will go away on their own
2. you can keep pounding away and they will get way worse.
i chose option 2 when i was an endurance runner and STILL to this day my shins hurt when i run. crazy huh?
a lot of runners back then told me to just keep running and they would go away, with some guys they do.. but with me wasn't happening.
so be careful you don't want this problem to become chronic.
