I have trouble swallowing whether my mouth is dry or full of saliva I cant swallow in the evenings after eating. I am eating a liquid diet veru little at that and it still bothers me to the point I have panic attacks and now feels like my throat is swollen inside. what could be wrong that would cause me to have a lot of difficulty tryig ot swallow. Have a very mild sinus infection that is clearing up and had an endoscopy done a couple weeks ago
