Re: frozen arms and hands

Could be nerve compression around the neck and collar bone while you're sleeping. I had this a long time ago when I was low weight and had bad chronic fatigue so I had poor posture from lack of exercise etc. It's called thoracic outlet syndrome I believe. Exercises to improve the posture and massage or manipulation of the area help.
I do qigong with a lot of arm and shoulder movements to open and strengthen that area. Tweet
