Nothing is "normal" in MS but this is something I've experienced and have dealt with. If it persists for a few days or a week, mention it to your neurologist. Have they done an MRI on your cerebellum and that area? If not that'll likely need to be done (it's a *long* MRI).

What you may also get is "phantom sensations" on your feet. Sometimes I'll get the feeling I'm walking on sand -- get it so strongly that if not paying attention I'll automatically lift my foot to wipe it off, then realizing I have socks and shoes on and there's no reason I should be feeling sand on my feet. 🙂

I too have a challenge with sensations to scratch my left side. From finger tips, to shoulder, it feels soooo good to scratch...lol I'm afraid I'm going to scratch my skin off, but there is no reason for the itch since it is under my skin. I believe I read something about it dealing with nerves.

I dont know if its normal but same thing happens to me. I know its MS nerve itch when I scratch and scratch and it does not relieve the itch at all. I usually end up with bleeding nail scratches before I figure it out tho. I have small scabs on my thumbs right now from itching/scratching so bad the other day and now I have numbness and muscle tightening but not releasing in those areas. Have you told your neuro?

I have this feeling intensely on my hands and feet, so I went to a dermatologist and it ended up being food intolerance that had worsened into allergies.
I searched online and found a intolerance test that you mail some hair to and it changed my life. I only itch when I break my diet, and it cost me less than a hundred dollars for the test.
I used Liberty Health Check, but I think they closed. For my son I used Check My Body Health.
