I am on disability for a variety of issues - multiple hip replacements, 3 neck surgeries (1 anterior, 2 posterior, low back surgery, DVT, and both shoulders, are the most obvious. I have started having muscle spasms and muscle cramps all over my body, especially om right arm/shoulder, my right chest, stomach and both legs - especially thighs. This began only at night and now is almost constant. I have been given potassium and magnesium along with a multi vitimin. Any things that I should be over concerned about?
