I had an endoscopy in 2013 with the diagnosis of mild reflux. The next day I experienced pain in my lower throat whenever I ate or drank ANYTHING which lasted for hours!  I still experience this pain and even a sip of water can start the discomfort.  I have lost 20 lbs.( I was already quite thin) and now I only eat or drink when I absolutely must.  My Dr. says I am swallowing air, but how is this possible and how could this be so life-altering? He also told me  "mind over matter" and not to let this problem consume me!  It has been almost 2 yrs.now and my symptoms persist.
