Why does my arm feel paralyzed when I sleep? This is called sleep paralysis, and it can be a frightening situation. You’re stuck somewhere in between dreaming and wakefulness, and you can’t move. 2) The nerve compression has led to a temporary paralysis (perhaps because you got stuck in a compressed position during REM). Compressing nerves can damage them.
Can you move your arm in sleep paralysis? You may be unable to move your arms or legs, body and head. You can breathe and think, but you may be unable to speak. The paralysis may last for only seconds or a few minutes.
Why does one arm fall asleep? Often, a person’s position is the cause. For example, the arm may fall asleep because a person is lying in a way that puts pressure on a nerve in the limb. Cases of positional paresthesia are harmless and generally occur when a nerve is under sustained pressure.
Why did I wake up and cant move my arm? While falling asleep or waking up, your brain helps the muscles in your arms and legs relax. With sleep paralysis, you regain awareness but can’t move. Paralysis is temporary and isn’t a sign of a major medical issue.
