I feel as though something is wrapping around my tongue , and coming back and forth in my mouth. I have had cat scans, tubes put in my nose and mouth. They can find nothing wrong, It was extremely painful for the first couple of years, now I believe I have killed all the nerves. it feels like there are pieces of my mouth that go up and down my throat . I will gag throw up, blood will pour from my mouth but quickly stop before I can figure out where it is coming from. Can u help
