Trimmed a black walnut on Tuesday, and my hands were all frigged up. Kept cramping and locking up and hurting. Wasn't much time climbing, maybe 3 hours. First thought is the saw, but I probably spent more time gripping a rope than saws and the ropes kinda need a harder grip too. They kept locking up on the steering wheel afterwards, right hand was worse than left but they were both messed up.
I may have gotten a tiny bit dehydrated but I never got fatigued or thirsty or anything like that. I had some caffeine and sodium and lots of water beforehand, and that's kinda my usual routine, a sugar free energy drink and water all day. Maybe some magnesium or potassium might help... or maybe stretching exercise for the hands, idk. Was bizarre, never had that happen before. Had to use my other hand to get my fingers off the steering wheel they were just kinda stuck gripping it.
Any thoughts or similar past experiences?
