I have read that this condition can cause muscle pain and cramps. It can also cause muscle weakness and fatigue. I fall into the second category, but the weakness is better than it used to be. I hope you were given some direction on remedies. One of the supplements I take daily is ribose. I was also directed to take Creatine, folic acid, carnitine, COQ10, and NAC. More recently, glutamine was added. No miracles yet, but I’m doing better.
