Last November 2011 (a month after the start of my PN symptoms), I had a TSH test and the result was 9.230. Prior to this, I have always been on Synthroid, .75 mcg (since my total thyroidectomy in 2007). I had a TSH test last May 2010, it was a little low, but it normalized after one month without adjusting my dosage.

Since November 2011, my dosage has been adjusted every month but it has been low. The latest was 0.100 taken last end of March. I am now at .75 mcg for 6 days and half of .75 mcg for 1 day. My result for my thyroid antibodies is negative. My next test is due end of April.

I am wondering if this has a bearing in my pain, or is it only hypothyroidsm that can cause PN? Is there anything that my doctor and me are missing in managing my thyroid? By the way, the T4 is normal.

Thank you for your inputs.
