TSH questions

[Margot49]

I have some health issues going on, long story.
I do see an Endocronologist and know I have probably 5 thyroid nodules and maybe a cyst.  Two thyroid nodule biopsies have been done, benign. I was due for my 6 month check up and she has ordered another thyroid biopsy. I had my blood work done but was too sick with ongoing stomach problems, nobody can diagnose, to make it to the appt.
Looking at my records, the last 3 TSH test results were
Nov. 2011. 0.80
May 2012  1.36
Niv. 2012   O.57

That seems like quite a drop to me but she does not seem concerned.  I really don't understand these results.

I do know that I have been having night sweats and wake up every morning sick to my stomach.  Had to go to ER a couple of weeks ago for irregular heartbeat.  

Anyone think any of this could be thyroid? I have had about every GI test done.

Thank you.  Due to all the Gastro issues I am dealing with, I had to cancel the thyroid biopsy.
I did have a halter monitor and should get the results of that tomorrow.  The ER doctor seemed to think it was from the Levsin and/or Dysclomine,mwhich I stopped.
Have had thorough GI work up and told I have SIBO which I was prescribed Xifaxan.  Strayed on Saturday and by the 3rd pill on Sunday was horribly sick.  I am having a terrible time with medications.  My GI dic said there is nothing else he can give me due to dry mouth and throat issues so I took another Xifaxan a few hours ago and am starting an upset again. Not your area, I understand.
At least I won't worry about the thyroid too much now, I was just questioning the big drop on that last test.  Thyroid problems run rampant on my mother's side of the family.
What I need is a good GI doctor.  I am not happy with Sutter Gould.
Again, thanks for your time

These TSH levels are all fairly similar and all normal.  It is not likely the night sweats and nausea are due to thyroid.  Most  nodules do not impact thyroid function.  The irregular heart rate and other symptoms do need additional evaluation but it is not likely stem from thyroid.
