Welcome to Healing Well! I'm glad to hear you've gotten medical attention for your symptoms, and it's good to hear your results have been positive.
GERD symptoms can be varied..."emptiness" is a pretty vague symptom. If it means a gnawing feeling, that would certainly be consistent with GERD/reactive stomach/gastritis.
I hope you find an answer to your problem very soon, and you get feeling better!
