I have had Chronic throat constriction for almost four years now. It is undiagnosed though I have been to doctors. A year ago I started reading this site and my symptoms so much matched some of the ones of LPR sufferers.
I had the procedure done that put a tube down my throat and they saw nothing. I have had two ENT's look down my throat with their little tubes and saw nothing. I have had the 24hr probe done - nothing.
The last doctor I was to was very familiar with LPR - even knew that it required 2 PPI's a day. He said He did not think it was LPR - maybe my throat could be a little red but he said I have anxiety and prescribed a nerve pill. I find this diagnosis to be wrong because I am not a nervous person. This constriction is there 24 hours a day no matter what I do though it is much worse as the day progresses. I have been on aciphex twice a day for about a month and don't feel any better. I have not stuck real close to the GERD diet as I have never once felt acid in my throat. I do have throat clearing and know if I go to be with food in my stomach I have pain in my diaphram area in the morning which is relieved by a deep breath. But they say I have no hernia.
Is there anyone who could give me advice? Am I misdiagnosing myself?
