Hi, I had a tonsilectomy in 2004. A few days later I got blood clots on the right side in my mouth. Ever since then I have trouble swallowing and when I swallow it hurts. I also noticed that my voice has changed too, my voice is deeper and I seem to have a lisp as well. I've gone to an ENT doctor, they've done an endoscopy and the barium swallow. It showed nothing. I'm so tired of my throat always hurting, so if anyone has any suggestions that would be greatly appreciated
