I have had an MRI of the brain in the past that was clear. (It was a few years ago, however) I have had tons of blood work, I am embarassed to say I do not know exactly what the blood work was for. It all came back clear.

No family history of anything similar as far as I am aware

I do not have any swelling or skin coloration. I do have temp change with the tops of my hands and feet getting extreme cold spots as I described.

I did have an injury to my knee about two years ago. I tore two ligaments, one on each side. There was no cause to this injury. I did not fall, did not twist it, did not pull it. Now that I think of it while most of my symptoms started long before the knee injury, most of my current ones either started right after that or got much worse after the injury.

I did look at the forum you suggested. I do not think that fits as my nerve pain and sensitivity is wide spread and not in one area. I also, do not have swelling or color changes.

Thank you very much for your response.
