Patricialyn,
This is almost scarry. I just realised that I wrote pretty much the same two years ago as you just did above.
Believe it or not but B12 vitamin, D vitamin and iron supplement helped me a lot overcoming the PN as it was associated with deficiencies. Do not be afraid of taking the supplements, if they have been discovered by blood tests. Iron as the only one has to be monitored by continual blood tests, so it does not get too high.
However, I have also been diagnosed with Hashimoto's Thyroditis - an autoimmune hereditary disease.
As it turned out my thyroid tests were in the normal ranges. Check if your TSH is in your blood work. (I assume that you have asked for copies for yourself or you should ask to have copies of all blood work at once.) In the affirmative is your TSH over 3.0??? Then you could have a thyroid problem.
Often the thyroid tests for antibodies are not taken if the usual results are within normal ranges. My antibodies were sky high - a sign of Hashimoto's. Receiving meds for Hashimoto's has really helped me. I still have the Hashi Headaches as I call them. When the antibodies go down these should be better too.
If you have relatives with different autoimmune diseases (and clearly you have), then you are likely to get one or more autoimmune diseases. Do any in your family have problems with the thyroid?? Goiters on the neck???
Here is the neuromuscular view of thyroid diseases:

I hope that you can use some of this, if not throw it away and keep on keeping on - do not give up!!!!
Take care!
