Hypo to Hyper in 6 weeks?

[Paikea]

Dear Docs,

I am a 31yo woman, diagnosed in late July with Hypothyroidism, from which I am symptomatic (fatigue, fuzzy brain, etc).  My TSH was 10.75 uIU/mL on the initial test.  I was started on 125mcg of Levothyroxine per day.  One day about 6 weeks later, the "missed heartbeats" I had been having for a while increased and I was having muscle pain in my chest that worried me so I went to the urgent care center.  My TSH was tested and had dropped to 0.062 uIU/mL.

My Internist recommended a reduced Levothyroxine dosage of 100mcg/day.  I had my levels re-tested week-before-last (mid-October) and it was only 0.072 uIU/mL.

Again the dosage was reduced, this time to 50mcg/day.  I start that tomorrow.

The doctor I saw yesterday stated that my body's reaction to the Levothyroxine didn't seem to be "normal" and I should definitely see the Endocrinologist.  I will, but the earliest I could get a new patient appointment is a month from now.  That's too long for me to be wondering what's going on, and even if I'm doing the right thing continuing on with the Levothyroxine.

I'm worried if I do, it could potentially messing up my thyroid even more, if that's possible.  I know it may take time to find a correct dosage, but could it be that I'm not supposed to be on it at all?

Please might you tell me what the quick and dramatic drop in TSH levels might signify?

Thanks!

P.S.  I now seem to have symptoms of both hypo and hyper ... fatigue and fuzzy brain, nervousness, poor sleep, headaches.  It's all very annoying!

Oops, I guess I thought I had posted in the right forum.  I'm new to this site, obviously.  :)

Thanks!
