Can your arm be injured from sleeping on it?

Yes, sleeping on your arm can lead to injuries or discomfort, such as numbness, tingling, or even temporary paralysis in the affected limb due to pressure on nerves or blood vessels. This condition, often referred to as "sleeping on your arm," can result in a condition called ulnar or radial nerve palsy. While these symptoms are usually temporary, prolonged pressure can lead to more serious issues like muscle strain or repetitive stress injuries. If pain or discomfort persists, it's advisable to consult a healthcare professional.
