Welcome to HealingWell!
Have you seen a doctor about
any of your symptoms? It's hard to say what you have, because GI ailments are hard to diagnose (they seem to overlap each other). However, it sounds like you could have GERD or maybe even H. Pylori on top of IBS. There are really a number of things that could be going on. Are you an extreme coffee drinker or Aspirin popper... You could have an ulcer.
After your hysterectomy did your doc advise you of any possible GI complications?
My suggestion is to see a GI specialist. S/He may want to do an upper and lower scope (EGD & colonoscopy). In the meantime, you may want to avoid acidic foods and caffeine. Also, obstaining from eating at least a few hours before going to bed.
I'm sure others will be along shorty to give you some ideas.
