Jamie,
I also have the lump in my throat. I was so scared it was cancer as i had lost my Mother to cancer, and then noticed the lump getting worse, i couldnt swollow well, i felt like something just stuck there, it was very nauseating. The Dr. did bloodwork to check thyroids, then sent me to an ENT whom did a scope test of my throat, then i was referred to a gastroentologist and he did a scope of the throat and stomach. All test showed no cancer, thank GOD, but showed the esophogas being very burned.
So now i take two nexium a day. It comes and goes now, but i have noticed stress makes it much worse. My Dr's had tried protonix, over the counter meds, previcid, prilosec, and now the nexium.
The good news is that it is not cancer, but it is still very scary. I will return to my M.D. soon for yet another follow up, but i would recommend having your Dr. run tests for peace of mind.
I had thought GERD was just the burning in the stomach and didnt realize it can appear as a lump feeling in the throat.
