Hi there
First thing I thought was have you stopped drinking suddenly as I know that can be a symptom.
I don't mean to play down your symptoms, but when we fixate on something it can make it worse.
Years ago I went to see a neurologist about a problem and he thought possibly I had MS. He rattled off a load of symptoms, one of which was tingling around the mouth. I kid you not, by the time I left his office, panicked, and got to the car, I noticed I had tingling around my mouth!
Suffice to say I did not have MS, thank God, but it showed me how the body can react.
If you suffer anxiety and are worried about test results, and possiby prone to hyperchondria (as I was at the time) then I wonder if that is what is happening here.
It got to the point with me that I could fixate on any part of my body and I would feel tingling.
Have you tried relaxing and not thinking about it? Does it get worse when you fixate on it? If so, I would bet that this is something that is happening for that reason.
I think you need to first try and relax and see if that has any bearing at all on your symptoms.
Take care xx
