I recently saw a hand specialist because of pain in my hand. (My crps is in my foot.) My fingers sometimes feel cold, but is not ice cold like my foot. Also no swelling in my hand. Anyway, the doc said he thinks it is more carpel tunnel and less crps. He is having me wear a wrist brace only at night. He said that would prevent me from sleeping with my wrist bent too far forward or backward, and help the nerve inflammation go down. He also said that carpel tunnel,could make my fingers cold. I am bring this up because maybe the numbness in your hand in the morning is because of the position of,your hand while you sleep, so could be helped with a brace. I know that immobilization isn't great for cprs, and he doesn't want me to use it other than at night, but it seems to be helping.

My had and arm are now cold in between nerve blocks. I go for one every 2-3 weeks. I'm trying now to go every 3 weeks just because I don't like getting them and I want to see what happens if I go longer.
Well, the last few times my RSD/CRPS arm is about 10 degrees colder than other arm. (I'm not exagerating). They measure the temps. right before the IV goes in. Just a couple of times I've gone just one week apart and temp. difference was only a couple of degrees.
I had rsd/CRPS for 3months before I started getting the nerve blocks so I don't know if the "cold" was always the case. My hand was greatly swollen before the nerve blocks as well.
