Anyone else get hand cramps after a days work?

I googled about cramp and I think I know the issue.  The tight gits didn't offer me a brew all the time I was there and I had a salty Chinese for tea and I was thirsty as fook when I got back.
Turns out cramp is often caused by a salt imbalance which happens when you let yourself be thirsty for too long, the Chinese wouldn't of helped either.
If it happens again I'll make a note of brews offered / food eaten and see if it's that.
Might have to get a prescription off my Doc that I can show customers that don't offer me enough refreshments

I get numbness when I sleep. It wakes me up & I need to lower my hand to get the blood in it.

I also sometimes need to wear a thumb support. It feels like my thumbs been bent back. Not always but at the moment I do

I'd say all plumbers work hard, Its the nature of the beast, just carrying your toolbox on its own is enough to tire a desk monkey, we're constantly going up and down stairs mostly carrying tools,equipment,rads,toilets etc etc, Its an active job, I start every morning with a coat and hat on and ten minutes after getting to the job they come off, then when you go out to the van for stuff you suddenly get cold again, I lose loads of coats,hats. pullovers because i forget where i put them,
And sweat, yea buckets full, My mentor was 25 stone, I never understood why he was active all day every day, but he eat a lot, smiley-eatdrink020 eat

Hehe, yeah mine's the same, I have a toolbox for waste fittings/clips, one for building tools, one for 15/22mm fittings, brass stuff and pushfit, another one with all sorts of different bits like close couple fixing kits, flush handles washer packs etc.  However my toolbag, the one I take first into any job must weigh as much as all of them put together
Problem is, whenever I sort it out I can never find owt...
