For almost a month, I have had problems following stomach flu I had on March 24th. Recently they have been very bad. My throat feels very tight, sometimes it feels like there is a lump it, and I have trouble swallowing and sometimes breathing. I also feel very dizzy and faint. Sometimes I feel pressure in my face/cheekbones. What could this be? I have been to the doctor, and my labwork is fine and they did not see anything, and I am supposed to be getting a scope, but dont have the money at this time.
