A couple things:
First, with thyroid, you can have normal TSH and still have a problem...have your doctor check for antibodies just to be sure. Also, make sure your doctor isn't going off "old" information (the new accepted values for TSH are lower.)

Next, the rhinocort...I'm not sure what that is. Is it similar to Nasonex or Flonase? If so, it would probably be fine to use if you have GERD. I use Nasonex daily due to some intense environmental allergies. If it's not, sorry...I don't know.

the rhinocort is budesonide spray, probly similar to nasonex, flonase, etc. As far as my thyroid goes, there is no visible swelling around my neck but boy it sure as heck feels like it! Also did some reading about post nasal drip (which i have terribly) and how that too can cause these symptoms. I am constantly swallowing thick secretions, clearing throat, and my ears always hurt. been taking the rhinocort probly two weeks now but don't think it's been long enough to get the full term effect yet. I would hope that my blood tests were figured using the most up to date numbers but they only sent me a paper telling me what was tested and they were all normal. i'm not sure if i even want to go to the gastroenterologist now if this could be all allergy related but i just don't know! i can't live like this everyday though, i know that! It's just constant pressure! it bothers me the most on the neck muscles on either side of the adams apple just above the collar bone. the muscles actually feel like they are tensed up all the time, they feel tight to the touch. Guess i should still get the scope work done though just to know if it isn't something in my esophagus.
