Suggest Medication For A Burning Sensation In The Throat

Two years ago had symptions of acid reflex at night waking up with a burning sensation in my throat. Then had a burning pain on my left side of stomach after I was belching. Had a video endoscope done and a month later an ultrasound scope to check my other organs. Can back all negative. Was put on Aciphex for 6 months then I slowly came back off of it. I was good for two years until recently I started to have a burning pain again on my left side. Been taking Aciphex which helps eliminate the burn. Is this gastritis?
