weird injury to both forearms

Hey, i've had a bit of a weird forearm injury for a few months now - I was wondering if anyone else had had or even heard or something similar, and what they did about it. Basically a few months ago I got back from a climbing trip to Thailand, bouldered a lot indoors for three days and then tried a route the next day and my forearms were incredibly sore. Not surprising I guess because i'd really flattened myself. Anyway, I took some days off but ever since if i dont quite warm up completely or pull hard on small, crimpy holds I get the weirdest sensation in both forearms. Sometimes when I do warm up its still there. Its hard to describe, when im actually pulling down it doesn't feel much different, but when i let go of the hold it feels like all the muscles in my forearm linking to my fingers suddenly release and recoil for a couple of seconds. It doesn't particularly hurt but it doesn't feel good at all. Its got a fair bit better in the last few weeks where i've just been doing roofy problems. Taking a few days off seems to help a bit too, and its not really there at all if im doing circuits - only bouldering. Pockets are okay but for some reason half crimp or even open handed full hand edges aren't. Sorry for the essay, its quite a weird thing to describe. I read a post further down about suspected compartment syndrome but dont think it sounds very similar (which is good!). Anyway, any thoughts would be great. Omar
