Initially I encountered wide swings of body temperture while in hospital -once in rehab facility it slowly subsided. Reurning home after 15 months I find that the warmer weather or home does seem to aid movement in my hands. My extremities do get much colder during the winter months.(We live in CT) .My rehab facility has a pool which is kept quite warm (92-94) and I really look forward to 3 sessions a week. My guess is that as I make more progress in activity hopefully that cold feeling will subside.
Maybe a move to sunny Ca would help!
All the best
