I have muscle cramps all the left side of my body, left arm, left side of the neck till under my left ear near the jaw, left side of chest and back and left leg. I take no medications at all. I don't know what's wrong. The arm spasm are the most unbearable. I can barely type this text.
I am having the same problem but I am on meds for my fibro & my depression. If you find something out I would love to know about it.
