G'day and welcome.
i'm not too clever on the sensible questions, but in my experience, a buzz tended to indicate that something might be repairing. followed by pain as the area comes back.
But more recently, my buzzes have been an indication that an area is getting worse and that numbness is spreading elsewhere.
So no clear answer here.
I'd take it easy if I were you. If it is MS, so much damage is silent before the sx shows and resting and allowing the body to repair or compensate is important.
There's a few antipodeans here. We're made very welcome by the U.S crew. There'll be one along in a minute to help you...
