So sorry: You have my deepest sympathy. I'm sure you often don't feel very well. I hope you're feeling better soon. Is there some question you might have that we could address for you here?

Muscle spasms?: Cramps usually mean that your are having painful spontaneous muscle contractions. Maintain adequate fluid intake and check blood tests for magnesium, ionized calcium & phosphorus. Avoid drinking alcohol. Statins for lowering cholesterol may also cause something similar.
