I get little tiwitches all over, they can last for several seconds. I can often watch them through my clothes.

I did, I think there must be nerve endings in our muscles and that's what is creating the twitch. I also used to feel like if I had an expression, my face would stick that way for awhile (w/o botox!!) ...so weird. I would get goosebumps all over a lot for no reason. The feeling of worms under your skin causing crazy itching going on. So, so many funky weird things.

yes I have it too, and many people I know do as well. Personally I think it's because I have begun to dial back on my activity level, and then I will get a burst of energy and do more than I have been doing. I think the muscles and nerves react to the sudden use and are trying to adjust. Like stretching an unused muscle. It's going to be a little sore. I think the twitching is merely that. As a result I'm working harder to do daily exercises and keep my strength and muscles up and in condition. That way when I do use them a lot they don't get so shocked by the activity.

I take Baclofen for mine know problem at all

They are also called fasciculations. It's also a symptom of ms regardless of what your neurologist says, although more often in those more progressed and it's often accompanied by weakness. You might look up videos on the subject to see if this is what you mentioned as twitching.
