They certainly are annoying. I sometimes have a day or two where I'll get small spontaneous jerks, mostly in the arms, but that passes. Just when that seems to be gone, it will come back for a bit. Also, weird sensations different places in my body and numbness, especially in my toes. That passes, too, then may appear at another place. It sounds like your GP doesn't think it's anything to be concerned about, but it is frustrating after a while. Especially when you have no idea why it happened. Will post what the neurologist says. My appointment isn't until November, unless they have a cancellation.
