I have the same symptoms as you after a month on protonix. Can you please let know if yours was an allergic reaction? I'm trying now Aciphex after three weeks of not taking any ppis, since I thought that I'm having an allergic reaction. I really hope this ppi will work without the side effects.
The lump in your throat after you took Zegrid may not have been a coincidence, as some people can get odd reactions to medications. You might find you would be OK on another
make of the medication.

Alternatively, the lump may be due to something else. Have you had a thyroid function test done recently, or has your doctor examined your neck for swelling?
Did it help when you quit taking the medicine. I have acid reflux and nothing seems to help me. I've watched my diet and took medicine and now I have a sore throat and a swollen tongue. I'm deeing a ENT now. Let me know if it helped to quit taking the medicine. Good luck!
