I had hiatal hernia surgery 2 years ago, since the healing period ended I can t eat without being sick. It feels like the food backs up to my throat. It happens 90% of the time at dinner, which means I don t eat. It seems to be less during the day. I seem to be sensitive to condiments, salad dressings, pickles, olives, grapes, apples and o and on. Never was before. Getting very old not being able to go to dinner with family and being sick all the time. If I get the me down then I end up gassy or having to head for the bathroom within 15 minutes. I ve had swallow tests, a scope down to my stomach. nothing
