PS.
I wake up with my hands completely numb and sensitive and dead every day- I am never sure if it is RSD or TOS as there is so much overlap between the two.
I do experience alot of the numbness you speak of on an ongoing basis.
I just don't use my arms/hands alot and have somehow become accustomed to it.

Dana brings up an excellent point.
When I get especially nervy and extremely hypersensitive to air I usually go in for a block as a treatment modality. Lower or upper body- right or left sides - depending on need.
I don't abuse the privilege as I want them to work for ever

However some of us are lucky enough to have health plans that cover blocks in our medical treatment while others are not.
I think it varies from program to program and state to state.

Good Luck
Breathe deep
It always works out in the end
