First thing to look at when muscles spasm and deform the extremities is magnesium.

Here is my magnesium thread:

We had a very generous poster come on here with a new lotion product made from magnesium that you rub on.... much easier than oral supplements IMO. I am now using it instead of oral ones:

Our local CVS has this. Yours might too. Easy, inexpensive and safe.

Many people respond to magnesium supplements because up to 70% of US residents are deficient in this mineral (because of dietary lack).

I would try this first.

Then I would get B12 testing and Vit D testing. If you have had this already and received "normal" as an result, I would get the results and post them here. Lab ranges in US are antiquated and no longer valid ( very low results are reported as "normal"). The B12 thread in the Sticky posts above explains this.

These interventions are inexpensive and very effective for some people. You must try them before moving on to more invasive procedures and tests.
