a random muscle in my left upper arm is twitching, sometimes leg ones do it too…how to stop and/or prevent?

Yeah, my calves in particular do that after every ride – it’s almost like watching waves rolling over the sea, most weird.

Might be electrolytes, or simply your muscle fibres repairing themselves. Try bananas for magnesium – that’s my tuppence worth of useless internet-forum medical advice 🙂

my calf muscles are mental too.

bits of them are twitching all the time – constantly – all the time, like, always. they never ever stop, ever, etc.

i say ‘bits’ because it’s never the whole muscle/group/whatever, it’s just small regions, about the size of a golf ball.

1 bit will twitch, followed a few seconds by a different bit, followed a few seconds later by another different bit, or one of the first bits, or another, then another, etc.

am i going to die?

I used to get this on my lower eyelid, strange

Its called fasciculation – looks like a bag of worms esp when calves get going. Brought on by fatigue plus you have may have a predisposition. Occasionally linked to some other neurological disorders (what they used to loosely call benign essential tremor, also motor neurone disease) but would not worry as most cases occur in isolation.

Best case benign…….worst case MND

BRUTAL Link you have been warned!!!!!

I get the eyelid thing when tired…and reckoned tiredness/dehydration has something to do with it…hic!
