This is exaclty What happens to me. About three years ago it happened to me every night for about a month but then it went away. And now it's back again my right arm falls asleep completely from shoulder on down. It's is very painful, annoying, as well as frustrating when your hving to wake up constantly in the middle of the night.
Try a softer mattress or a memory foam or pillow-top pad. Too-hard beds can cause pressure points and misalignments. Don't forget to get the right pillow to keep your neck straight with the spine. This applies whether you are a back or side sleeper. Dunno about tummy sleepers since I haven't for years. But a bit softer sleeping surface stopped my arms going numb! Worth a try.
I've been experiencing this for a few months now. I noticed that when I slept in one of our beds in our Lake house (for the weekend) that the pain would start. Sometimes my arms go numb, but it would be the usual kind. After recently sleeping at the Lake, the pain would start when I would "wake" my arm up. Then when I would get home, (sleeping in my own bed with my pillow), the pain would get better, but still be present. I decided to change pillows at home and found that a flatter pillow slightly under my back (so that my back and neck are straight) felt much better. Then I changed to a large, soft body pillow and found that I could wrap it under each arm (like U; with my head at the loop in the bottom) and that pretty much took the pain away. I've had 2 nights of good sleep so far. I'm not sure what it is, but the pillow height seems to be an issue. We are going down to the Lake again this weekend and I'll be taking the body pillow with me. I'm not sure what started it, but if it continues to be an issue, I'll see what my doctor says
I had the same issue where at worst both arms were falling asleep, sometimes just had numb fingers on my left hand. You can find more by searching under the medical term "idiopathic peripheral neuropathy" or just "peripheral neuropathy". This just describes the symptoms, not the cause. However, for me, I noticed that the symptoms were less severe when I'd eaten spinach, did some research, and have had success with iron supplementation (I'm using Fergon). Copper is required to utilize iron, so that could play a role, and Vitamin D deficiency may also play a role.
Im glad to come across this because i've been having alot of problems with my arms and hands falling asleep. Especially when I wake up in the morning. I've also been having throbbing in my toes and finger tips. I've recently visited with an Internal Medicine Dr. because my General Dr. was not being agressive enough.
Im under alot of stress with my husband being overseas so I keep hoping this is stress related.Im also on the computer alot too.My Internal Medicine Dr. has ordered numerous lab work and I feel were finally getting somewhere.
I like all of you have the issue of my hands going numb while asleep. In addition they sometimes go to sleep while I'm driving or crocheting or reading or any number of activities. Now after a particularly bad night of the numbness (very painful) I'm having trouble moving the middle finger of my left hand. Someone had mentioned to me that it might be a circulation problem but I just don't know. Does this all sound like what you all are experiencing?
