Hi Lizzard77, I'm so sorry to hear about the tumor. I went to an ENT, and he said he assumes it's just acid reflux since I have a history of acid reflux problems. He told me to up my antacids and come back in 6 weeks if it's still going on for further testing. I'm also having difficulty swallowing now and I frequently feel like something is swollen in there. I know I have a cyst on my thyroid. I wonder if that could have anything to do with it. Hopefully it's just acid reflux for me. I hope your biopsy goes well. You'll be in my thoughts and prayers. If you get a chance, keep me posted on how it goes!
