I am currently having many of these same problems. Tickle in throat, sharp pain, cough, tears, nose dripping. This has been happening for
the past 5 months. I've been to a ENT. He said it was my tonsils. I had them out. At first while I was on meds during my recovery from the surgery the symptoms stopped. But after I stopped taking the pain killers anti-biotic and the steroids the tickle came back. I've been taking Previcid for acid reflux but this has not stopped the attacks.
