what causes numbness in arm
An injury to the nerves in the arm, neck, shoulder, or even the back can cause a numbness sensation to set in the right arm. Injury can include compression of the blood vessels, an infection, or tissue scarring. Incidents such as frostbite, a herniated disk, or an animal bite may cause damage to the right arm.
A common cause of temporary numbness of the right arm is carpal tunnel syndrome. As a specific injury to the median nerve at the wrist region, you may feel tingling and numbness in the lower arm as well as your hand and fingers. You may also experience pain with this disorder.
Numbness in the right arm caused by a stroke may be linked to the functions of the left side of the brain in most people. This can affect your concentration and speech. Please note that for many left-handed people, the right side of the brain controls the language function.
Numbness in the Hands. Numbness in the hands is a sensation of loss of feelings in the hands, often referred to as falling asleep. Symptoms of hand numbness are tingling, pins-and-needles, prickling sensations. Sleeping on your hands or holding your hands above your head for a long period of time will cause numbness.
