It sounds like you've got a lesion that's aggravating certain nerves. I've had similar sensations.

It's nearly impossible to describe how it feels without sounding like a throwback from Woodstock! My Neurologist used to tell me he enjoyed hearing my vivid descriptions of various symptoms I was having.

I'd just keep a log of my symptoms and when they peak. Mine always get worse when the barometric pressure outside is low and fluctuating. I can always tell when it's going to rain.
