Was diagnosed as hypothyroid almost 2 years ago and began on generic levothyroxine.  I felt GOOD for about 2 months, then the symptoms began--nausea, heart palpitations, aches and pains everywhere.  My PCP upped the dose a bit, but nothing changed.  That went on for at least 6 months, and he finally sent me to an endocrinologist.  She tried 50mg brand name Synthroid.  Again, I felt really good for about 2 months, and the same symptoms began again.  Because I was going away, I went to ER and they kept me overnight, testing every organ in my body and finding nothing 'wrong'.  Noone considered that Synthroid could be the problem.  So, there I was on Synthroid for a year, feeling miserable and making everyone around me even more miserable!

Finally, after I did research online, the endo tried Armour Thyroid, which also worked 'great' for about 2 months, and the same symptoms began again!!!  On my own, I cut dosage from 60mg to 30 mgo (am cutting 120's--since that is all my local CVS has available, and my 90-day supplier has none).  THAT worked for 2 months--hadn't felt that well in over a year -- and now the same symptoms are back AGAIN!!!  

I live in the Boston area, where there are more medical schools and world-class hospitals than anywhere on earth!  I like and trust my endo, and I know she's willing to try anything I want, but I'm at my wit's end.  I'm thinking that no med might be better than anything I've tried so far, since I'm on such a low dose.

Anyone else have these symptoms on Armour?  I really thought I had found the answer, and it is depressing that it doesn't seem to be.
