pain in my feet since before my son was born. It was like walking on broken glass shards, esp in the morning when I first got up.

30 yrs ago I did not think it was a thyroid issue..or even PN. I thought it was from standing on my feet all day for 13 hr shifts, etc.

After my son was born, my goiter grew. But my blood work was fairly normal.
Then I had an episode, resembling a heart attack, which was not the heart at all. But during all those tests, my doctor recommended an Endo. He was rude and said it was all in my head...but relented to a technicium scan because he felt the swelling. The rest is history... after being raised to 75mcg Synthroid, I stablized there. My feet went back to normal after about a year. In the beginning there was a lot of tingling--which was them waking up.
My carpal tunnel improved also.

The way it works is that hypothyroid people produce a tissue substance that clogs the tarsal and carpal ligaments. This creates the PN symptoms.

Even today if I have alot of edema, from overusing salt etc, I get some symptoms back. So I use a diuretic about twice a week to control that.

My last TSH was 1.24, down from 2.0 from a year previously. As long as it is below 2, I don't push for increase. I know the connection between over use of thyroid and osteoporosis.
