Paresthesia or limb numbness. What it is and how to deal with it

Waking up to find you’ve lost all sensation in your arm or leg is not the most pleasant way to wake up. While common, the sensation of pins and needles, or worse yet, no sensation at all, is called paresthesia.

The non-medical cause of paresthesia or numbness is usually the result of laying directly on a nerve or a set of nerves. While sleeping, sometimes a nerve becomes pinched in an arm, leg or foot resulting in no feeling.

This pinching or compression of the nerve happens when pressure is exerted by the tissues, bones, muscles and cartilage surrounding the nerve. This pressure disrupts nerve function, creating the pins-and-needles feeling or the loss of all sensation.

Once the surrounding pressure is relieved, the nerve or set of nerves, returns to normal and sensation returns.

If you suffer from burning or pain that radiates down an arm or a leg, you may be suffering from more than just a temporarily pinched nerve. Weakness, numbness or pain when you change positions may be the result of a sciatic nerve or other nerves being pinched.

In these cases, it is best to visit to your doctor or chiropractor for a professional diagnosis.
