Hey there, I'm in the same boat, I have just about all those symptoms also. I'm not sure either if its anxiety thats what the doctors are saying but I think they just brush me off. I thought anxiety symptoms go away after like 30 min, mine stay all day too.
That buzzing can definitely be due to anxiety. I had it when I was going through a particularly bad patch. Plus the odd facial feelings too. And the dizzyness.
Anxiety can cause day in day out symptoms as well as the more short lived ones.
My experience has been that anxiety phases attack one part of the body ie one "flare" will cause lots of indegestion, tummy, burping, air swallowing, lump in throat, then I'll get over it (paxil worked for me) then the next time it was more nervous system with dizziness, nausea, headaches, buzzing etc. then the next time it was heart, palpitations, chest pains, racing heart, sweating.
You guys will get better and when you do, those feelings will go away.
Good luck.
I have the exact same symptoms. It is what generalized or floating anxiety is. There is a great article that I reference on my profile (first journal entry) that does a great job of explaining it.
