Dear Doc,
What is the definition of muscle spasms? How are they different from muscle twitching? I myself have muscle twitching, some twitches you can't see, some you can see, and some twitches actually make my thumb move, or my shoulder will sometimes jump or shake a little. Can all of these symptoms be muscles twitches or are they spasms? I've been to two neuro's, and they both think I have BFS. I've had an emg done in May which came back normal, no mri taken. One other question I have pertains to another symptom I have. If I were to hold my arms straight out in front of me, my left arm (at the base/arm pit area) will seem to tremble/shake, but my right does not. My left arm does NOT feel weaker than the right though. Can this symptom be attributed to the BFS. My left arm does have more sypmtoms than any other body area, but all areas of my body at some time have symptoms on and off. Thanks for your answer in advance.
