Hi.
I am post RAI 5 yrs ago. Was fine on levoxyl..levels were great.
I moved and changed insurance. They put me on synthroid. I took .137 and my tsh was 4.7 so they upped it to .150 and my tsh actually went UP to 6.9!

I moved to a very high altitude city with colder weather than I was used to and I moved from sea level (does this matter?).

Has anyone had this happen? What on Earth can be the cause? Now I am on .175 and am praying to get some energy soon!

Thanks for any help. I would really appreciate any comments.

Sara
