I was diagnosed with SPMS in 2009, Mayo says I have had it at least back to 1980.. I have the same issue. Luckily it comes and goes, sometimes lasting weeks or months at a time. Most all of my lesions are in my brainstem and spine. Talk to your Neuro about it, the one I had when it first started wasn't too interested when I told her. I know it doesn't feel like it now, but it is just one of the minor things you learn to live with.
It's certainly worth checking with your doctor. For years, long before my diagnosis, the tip of my nose and my chin were numb, and tingly at times. Sometimes the right side of my mouth will be numb, and I'll drool unexpectedly because it seems to be a little loose.
Dental work can cause this problem too - it's not necessarily MS-related.
Hi, what you are talking about doesn't sound like MS to me, but I'm no medical expert. There are a few things that can cause this type of sensation in your mouth and if it keeps up, be sure to talk to your doctor. I hope your symptoms pass - that has to be so irritating.
