I would suggest it's not your forearms being weak, possibly just overworked. I used to do EVERYTHING for my forearms (rope climbs, towel pullups, wrist curls, bicep curls, fingertip pushups, basically anything I could think of) and now after a few weeks of bagwaork i start getting shinsplint feelings in my forearms and it sucks big time.
Ahhh, a n00b here to spam his link and give great advice that nobody could think of THREE GODDAMN YEARS AGO. KEWL!!!!!!!!
low in strength or low in strength in relation to the amount of work he does? Marius pugianowski could wank all day and he'd get a sore forearm. Doesn't mean his forearms are weak.
I used to have a similar issue. I strapped (tubi-grip bandages) my elbows whilst lifting when the pain was bad and it really helped. I also started taking glucosamine & chondroitin which after a few weeks pretty much resolved the issue.
