Numbness is a broad umbrella term used for an unexplained physiological immobility or lack of feeling any pain or loss of sensation in any part of the body. It can be brought about by blunt force trauma to the head, or even by something as harmless as sitting for a long time that numbs your feet. Numbness also strikes immediately after specific injuries like burns and is associated with a pins and needles sensation. It happens due to excessive pressure on a nerve, for example in carpal tunnel syndrome or irritation and damage of nerve ends.
HOW IS NUMBNESS DIAGNOSED?
Numbness is very common after getting up in the morning especially if a particular part of the body hasn't moved in a long time.
