It's concerning nm diseases - ALS, in particular. I have been petrified of having the disease since I began experiencing muscle twitching (all over) almost two years ago. During the time, the only other objective symptom I've had has been left shoulder weakness, which has been diagnosed as a rotator cuff issue.
I have had a total of seven EMG tests done, with the last one being under a month ago, with a neuromuscular disease specialist. He tested eight spots in my left arm and leg.
Problem is, about a week after the test, a muscle just above my RIGHT knee started twitching, multiple times a day, about 20s at a time, and for just under two weeks. From what I understand about Benign Fasciculation Syndrome, these "hot spots" are normal, and everyone gets them, and they eventually go away.
That particular twitch has indeed gone away, but of course, my worried mind keeps being worried. If it were the disease in progress, wouldn't that twitch have remained until the muscle was dead? As well, wouldn't I notice weakness prior to the twitching setting in?
