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.

I believe my hypo preceded my PN. As far as I can guess, hypo can affect every cell in the body; therefore it would be surprising if it didn't affect nerves. Nerves need T3, so a short- or long-term lack of T3 is going to cause problems.

What were your T3 levels like, if you don't mind me asking, when your TSH was over 9?

I suspect I've been hypo for a long time - long before I got tested - and it gradually became a bigger problem.

Stress can cause problems for the adrenals; when that happens, the thyroid issues can start; if they continue, you can get PN.

My research lately has led me to several doctors' books where they say you need to fix your adrenal function before hypo treatment. Even Armour's warning says adrenal insufficiency is a contraindication for taking the popular supplement.

My new plan is to take Lugol's 2% solution for one week to one month. This Iodine detox can take care of significant problems that are constant chronic stressors; e.g., heavy metals and parasites. Dr. Mark Starr advocates using it and claims great success with his hypo patients. I've also read lots of positive reviews online from users.

Today I bought ten more medical books, mostly about thyroid health and iodine. (I also got one or two on salt; I'm switching to a new table salt and cooking salt that will cause less stress.)

P.S. It seems hypo tends to reduce circulation to the skin which could prevent nerves from getting what they need.

T3 has never been tested.

When you mention about stress causing problems to the adrenal, do you mean the stress of daily living or something else e.g. metals, etc. (i think you are referring to the latter, but just wanted to make sure).

Whew, that's a bunch of books!!!! I am sure you can find information that you will benefit....

Thank you.
