Hey Rivkah,
I am so sorry about the problems you are having ((hugs))
I don't have nail loss. My nails started to grow really fast when I was diagnosed with RSD. It does say that nails can become brittle with RSD though. I am sorry that I can't help you further, Rivkah.
I really hope that the new RSD speciallist you are going to see will be happy to treat you, you deserve to get better after everything you have been through. I really admire how you are coping ((hugs)). I am hoping to go and see a new PM doctor soon. My PM doctor is pretty rubbish and doesn't really understand how much pain I am in.
Take care and sorry that I can't help you that much
GOOD LUCK WHEN YOU GO AND SEE THE RSD SPECIALLIST
Love
Alison
