How do you know if you have nerve damage in your arm?
Symptoms of Nerve Injuries of the Hand, Wrist and Elbow Common symptoms of nerve injury include: Loss of sensation in the upper arm, forearm, and/or hand. Each nerve supplies different areas of sensation in the upper extremity. The pattern of numbness can help guide the surgeon to the specific injured nerve(s).
Can you get nerve damage from sleeping wrong?
A pinched nerve can be caused by sleeping in an awkward position, sitting in one position for some length of time, a sudden twisting of the body or some form of accident. When patients have an irritated nerve in the neck, they often feel the pain down their arms.
What happens when you lay on your arm too long?
It may happen if you’ve lain on your arm or otherwise put pressure on it. This prevents the blood from flowing correctly to your nerves. Poor positioning may also lead to pressure being placed directly on a nerve. The nerves react to the lack of blood flow or pinching by causing momentary tingling.
Where should your arms be when you sleep on your side?

What happens when you sleep on top of your arm?
The radial nerve straightens out the arm and lifts your wrist and fingers. The ulnar nerve spreads your fingers. Although Dyck says the exact physiology isn’t completely understood, the effect of compressing any of these nerves in sleep — when you sleep on top of your arm or pin it underneath a partner — is like stepping on a garden hose.
Is it bad to sleep on a nerve?
Yes – under some circumstances. Normally if you sleep with pressure on a nerve it is painful, which would wake you and prompt you to change position, removing pressure from the nerve and avoiding damage to the nerve.
What happens when you fall asleep on a limb?
It is a temporary phase that means nerves are coming back to life.” Someone who falls asleep on a limb is unlikely to do major damage to the nerves, Dyck says.
