Question

After lifting weights, I have been waking up in the night with numbness in both arms. What causes this?

Answer 1

Sounds like some sort of nerve problem. Perhaps the technique you are using is incorrect or you are causing nerve impingement.  

Answer 2

Hello, this sounds like a neuritis thing- inflammation of the nerves of the arms, possibly higher and in the brachial plexus/ the neck region.

If you have had any optic neuritis (temporary blindness) in one eye, or unsteady gait- then suspect something like multiple sclerosis.
