Permanent feeling of lump in throat - barium swollow

I've been feeling that there is permanently a lump in my throat. I have been on anti Acid reflux meds for 4 months and it hasn't helped much. My ENT about 2 months ago put a camera through my nose and down my throat and said that my throat is swollen and prescribed Nexium for 60 days. It improved a little but after a while the feeling of the lump increased. I went back to my ENT who once again put the camera down my throat and again my throat was swollen. She referred me for a barium swollow which indicated that " relative stenosis of the GE junction which delayed barium transit into the stomach" and " GOR present. I am still waiting for my ENT to phone and explain. I have not noticed a dull pain in my upper stomach before but since the barium I am noticing it. Has anybody had anything like this or could anybody shed some light on it. Thank you in advance
