The only time I've ever felt this kind of twitching was after my neck and back MRI a few weeks back. IT was really strong then.

Today my body keeps twitching every so often, maybe like every 5 minutes now.
I'm not sure if it is even twitching.

It Feels like my body is vibrating hard, I'm not sure why this is.

Anyone know?

I have this on occasion...I forgot the term for it...I get used to it the bad time is when you're sleeping and it awakens you...

Luke, from now on you can bet that anything you feel, odd or weird,
is MS. But, just in case it isn't, you should call your Doc.

hi skywalker

The feeling of constant vibration feeling? ys I have had that now for a while. The neuro doctor told me it was all because of my small fiber neuropathy. But I can not quite understand it.
In the evening, that internal vibration comes on strongly. I have parashesia of arms, and at the end of the day, my hands are actually trembeling and weak.
Is this how you feel?

I had that internal trembling during one period of my life, perhaps 30 years ago. It lasted a couple of months and I took Choline to control it. I don't have that now.
But I am a champion twitcher. I call it Myoclonus. Back and legs jerk, mostly at night after I have relaxed in bed. I control it, as I've often said here, with magnesium and calcium. I have close to complete control with that, if one compared it to how it would be without magnesium...I went one night without it in the hospital and never stopped the myoclonus once. They should have got me magnesium as I asked. They were too busy.
I hope you've tried mag, Skywalker. MS doctor prescribed it for me long time ago.
