Background: I've been experiencing pretty much ALL of the hypothyroidism symptoms, especially fatigue and mental fogginess for a few years now and they are becoming progressively worse and somewhat debilitating. In addition, for the past six months I've been having tightness and pain in my left chest area and some pain in my neck/throat too.

My TSH two weeks ago was 0.88 (range 0.35-5.5). I just got new labs back today and they are as follows:

TSH 1.86 (range 0.35-5.5)
FT3 3.5 (I don't know the range yet)
FT4 1.23 (I don't know the range yet)
B12 270 (range 211-911)

My B12 two years ago was 282 and the doctor said to take a mutivitamin which I do. I am also a regular meat and cheese eater.

Any thoughts? Is it normal for my TSH to more than double in two weeks? Could all of my symptoms be caused by my somewhat low B12? I've been reading a bit about B12 and I've learned that many people have symptoms at this level. I really want to feel better!!!

Hello, Yes low B12 and low ferritin are very common in hypothyroidism.

I do want to tell you,as there might be some to disagree with me, but the TSH is so useless. My sister had a TSH of 1.92 but her FT4 and Ft3 were quite low and she was so hypo.

Without knowing what your ranges are for the Ft4 and Ft3, it is hard for me to really judge.

If you could post the ranges it will be so much more helpful. My guess is you are hypo or have hashis. I believe a lower TSH is seen in people with Hashimotos.
