Why does my f-in arm go numb when I sleep?

[danielson]

No loss of power. I haven't seen a doctor because I just figured I was cutting off circulation. (I tend to sleep coffin style, with my hands folded over my chest. ) It happens only when I leave my arms folded up like that for a while, watching TV or in bed. As soon as I stretch them out again, it goes away.

So - am I supposed to be worried?

supreme's answer pretty much covered it all, sorry, im working for a few weeks in a place where i dont have regular internet access....

but pinky and ring finger is nerve distribution (ulnar nerve) and therefore the nerve is being affected according to your history

I wouldnt be worried but i would see a doc just so he can do an exam

nerve pressing will cause this also.

All the responses above are really good... don't forget nerve glides. Sometimes it is your nerves not your blood. I think the last time I posted I wrote on nerve glides too... ha. Also, you might try massaging, and icing the shoulder and surrounding area for a little bit to get swelling to go down (if it exists).
Another thing if none of this helps, would you happen to be getting big shocks down your neck and into your arm with certain head and shoulder movements?

Are you sleeping on it

 

[roidpuple]

because the nerve suply is blocked..

Could be several issues in play. Thoracic outlet sysndrome is possible, as is poor sleeping positioning. These would be my first guesses.
Incorporate more stretching into your routine, this can help loosen stiffness which can lead to/exacerbate the problem. Prolonged hangs [2 arm + 1 arm] from a bar can help w/ shoulder girdle stiffness.
You should get eval'd by your doc. This could be postulated on all day on the WWW, a thorough hands-on exam is what you need here.
Hope I helped.

Happens to me when i am on cycle, not sure why obviously something with blood flow. The best position i found was on my back with arms on stomach or fingers interlocked on chest.
