I've been seeing a chiropractor for many months now. I've learned that the pain and/or tingling I get in my hands at night is most likely a pinched nerve. Told the chiro about it and he said try moving your head around, holding positions for just a moment to see what happens. When I find just the right spot, the pain or tingling starts to go away immediately.

Since your pain is in your arms, my chiro would say that comes from the neck vertebra. Anything below that comes from the lower spine.

Try moving your head around and hold it in different places for just a moment. If the pain is on the left, move your head to the right; anything opposite of where the pain is.

Hope you find relief in some way!
