Have you had your thyroid checked recently?
I just this week found out that my blood tests show signs of thyroid disease and my investigations showed that it causes hair loss to the point of balding. I have also noticed alot of people with CRPS have thyroud issues. Both also thought to be auto-immune issues. Its worth checking out. I havent had the hair loss but unfortunatly a little hair gain on my neck
but apparently it treatable and you just need to add an extra tablet to the pile we already have to take.
It might be worth checking out. Its much easier to treat than CRPS! Good luck.
