Many of us Lupus sufferers also suffer from Fibromyalgia and one of the most common symptoms of Fibromyalgia is muscle twitching and spasms. Other symptoms include: burning muscles, numbness and tingling sensation; dry mouth and eyes, slow and slurring speech, coordination and balance difficulties.
Your muscle twitching may also be a response to extreme fatigue (a common symptom of Lupus and Fibromyalgia) or some of your medication. The problem with muscle twitching is that it is a common symptom for several diseases, and for some things that are not *disease* in origin. One of the most common ways to determine the origin of the disease (whether disease oriented or not) is through blood tests. A rise in certain muscle enzymes is common when the problem is disease related - doesn't happen in cases other than disease related.
As I said, the most common *disease-related* causes for muscle weakness include: lupus, Fibromyalgia, polymyositis, and myasthenia gravis. The most common *non-disease-related* causes for muscle twitching nclude: medication effects (steroids and Plaquenil, for example), or electrolyte imbalances.
I hope that this was helpful :lol:
