Nan - I have exactly that feeling - bristly worms squirming up and down my nerves or blood vessels ... as well as dreadful nerve pain in legs at night - and burning skin, aching, awful cramping, and a feeling like iron spikes are being driven into the bones of my feet ... I find a hobble around the garden before bed helps, some CBD oil sometimes too, a bath, some lemon myrtle tea, lots and lots of magnesium spray or cream ... but who actually manages to do all that every evening on top of the twenty pills we all take etc etc? Sunkacola's suggestion of a TENS machine is probably a good idea to try ...
We just do the best we can, don't we?
