Hi Kazzar1958
I had twitches for a time in my upper arm. They were not painful but lasted for a few hours and then came back again for about a week. They haven't been back for awhile but that doesn't mean they won't. My neurologist told me they were BFS.

Since the onset of my symptoms I have had them in my calves. They would keep me up every night. I still get them some nights but they are much milder. Some things that have helped me:

Slow mag 2 times a day
Morton's Epsom Salt lotion
10's machine
banana or coconut water
Gabapentin (I think it has helped with the twitches but I am not pushing this drug. I'm planning to try getting off it soon.)
