something stuck in my throat

i have been looking at all ure questions and answers and i would like to say that i had severe acid reflux for about a year until went for the edoscope (camera down throat) witch resulting in me having a hiatus hernia so i thought ok good ive now found out what the problem is..WRONG  2 wks into the tablets i had severe dry mouth and felt like i was choking i had to sip water as i had a feeling of bubbling up in my throat but the more i drank the less i felt the lump i mustve drank gallons of water and i stayed up all night afraid i wouldnt wake up so few days have passed and i still have this lump on my throat like a golf ball stuck there or a hair stuck in my throat so then i panic and then u feel sudden swelling in the mouth so i try to keep calm which is extremely hard on top of this my results came in from the biopsy they did on my stomach and the doc said i have unusual cells in my stomach relating to allergies  so am being reffered to ENT  hopefully they willl see or reassure me theres nothing wrong with me ...if theres any1 else out there like me please get in touch
