Just wanted to post this in case anyone else has this problem and hates going to the doctor. For almost a year I have had my hands go numb when I am sleeping. The way I sleep best is putting my hands under my head so I thought it was just poor circulation. Well after a while it started happening when I would be on the computer AND when I was at work typing. I found out that it wasn't poor circulation but my neck was causing the problem. Then I was told that if I do exercises by slowly moving my head forward and make a circle from one shoulder, to the back, then to other shoulder and forward again and do this several times that it would help. Well it helped when my hands were already numb but afraid that I always forget to do the exercises and so I started looking for an alternative method. I found a Ergonomic pillow that works great.
I ended up buying 2 different types of pillows and the first one I got did not give my neck enough support and so it didn't work. I then went out and purchased another one with better neck support and it works great. Since they are not the most comfortable pillows in the world, I would have it on my bed and use my nice fluffy pillow until I start having a problem with the numbing hands (sometimes I will go several weeks without a problem) and then I would use the ergonomic pillow for several weeks, then go back to my fluffy pillow again. I would rather do this than go to a chiropractor every couple of weeks and is definitely cheaper.
