ENT----I have a pinching sensation at the base of my tongue similar to that feeling you get when you are about to vomit. My stomach is fine. I had a dull ache high on the back side of my throat behind my sinuses. I saw a dr. and she found swollen lymph nodes on either side of my neck and gave me cephalexin. That ache might be a bit better, but the drawing sensation at the back underneath part of my tongue is worse. Any ideas?
