I've read online that itching can be a sign of MS but on other sites it doesn't list itching as a symptom.

My main symptoms are:

Random body itching (usually lasts 1 hour or so) when I do scratch the itch, it seems to go away
Some muscle twitching in calf area
Random body nerve zaps that come and go
Some minor tingling in left finger and left forehead area

My B12 level was 850+
