Bit of a weird one that I haven't been able to find any information online about. Will try to get to a physio when I can but just wanted to check if anybody has any ideas...
Fairly often when I sport climb at my limit, around 6 hours later I get the worse pump imaginable in my forearms. Certain route styles seem to aggravate this more than others, latest one is a 25m vertical crimpy route that is infamously pumpy.
The pain in my forearms isn't a normal pump you get from climbing, it is normally painful enough to wake me up in my sleep, and I've had it last up to two weeks (though more commonly it lasts a couple of days). The pain is deep in my forearms and making a fist or opening my hand is agonizing when it happens. My hand feels locked in a half open position.
Stretching out the forearms (and ibuprofen gel) normally helps to alleviate it.
I've had it happen after only climbing a single pitch, so didn't seem related to the quantity of climbing (though definitely related to intensity). It has happened today after two goes on a route I'm trying. I didn't feel trashed or anything when at the crag but have just been woken up by the pain in my forearms at 3am
Thanks in advance (also hello, have been lurking for years but this is my first post)
