I find this same feeling in my legs and feet as welli would say it's the fibromyalgia but docs keep telling me it's my diabetes all I know is it horrible feeling like this I have suffered this illness for nearly 23 years but tomorrow is a new day and maybe it will be a better one we can only hope and pray

It could be neuropathy. I have both neuropathy and fibromyalgia. They're both neurological, so not surprising.

I get a shock like feeling g in my lower right arm when I move it a certain way. Very strange. I haven't mentioned it to doctors because it's something I think they will blow off, and it's something that doesn't bother me too much.

I get the same sort of pain but in my outer thigh, it goes into spasm and have to breathe through it like you do when in labour. Then stretch like you and feet go into cramping.
