This is something I've had a lot with varying intensity (completely numb to tingles) from the fingers up into the shoulder area. There are so many muscles and trigger points in the shoulders and lower neck that can cause this through muscle tension I never worry about it (but it is irritating). So I agree with Dav and Sandra - probably has to do with sleep position if you wake up with it - a new pillow may help but really the only thing you can do otherwise is to change position, try to get it to relax, get the blood flow going, and it will stop. If you ask a professional (physical therapy, therapeutic massage, etc.) they will have you come in for treatments and that may work if that is available to you. It just gets expensive - not to mention redundant. I usually just try to stretch the area and see if I can work whatever area that will stabilize it to get some balance back in the muscles so they are not pulling so much in one direction. I am guessing with this part of my self-therapy since I have only books and no professional training in this - just years of experience. It does work for me a good part of the time and saves me trips and the expense for an appointment.With pnhe I've learned that for the most part - I am on my own. So I do what I can and usually it is enough. It definitely gets worse when I am not exercising and when I spend a lot of time working (sitting, typing, and esp using the mouse.) LOL Sandra I've tried that zombie sleep position also.
