I have a continual sore throat, laryngitis, drip in the back of my throat. I have bad allergies and asthma too and am often congested. I was in the hospital earlier with diverticulitis with an abcess and minor bowel perforations and was treated with flagyl and cipro numerous times which left my intestinal tract a mess. Now I don t know if what I m experiencing is Gerd, allergies, or a combination of things. Can Gerd cause head congestion , sore throat, and difficulty with breathing?
