Quick Answer

Right-hand numbness is generally caused by irritation or damage of one or more of the nerves in the wrist and arm.

Full Answer

Right-hand numbness is usually temporary, although if it is caused by problems with the brain or spinal cord, it may result in partial paralysis. Electrolyte imbalance caused by deficiencies of vitamins A, B5, B6,

B12, and D, and minerals such as potassium and calcium can also be a cause. Physical injury can also lead to loss of sensation of the right hand. Repeated compression of nerves in the carpal tunnel causes carpal tunnel syndrome, which in turn causes numbness in one or both hands. Other health conditions that cause right-hand numbness include ganglion cyst; cervical spondylosis; Raynaud’s disease (numbness due to stress or cold temperatures); syphilis; type 2 diabetes; vasculitis (inflammation of blood vessels); and Guillain-Barre syndrome (a rare disorder in which the body’s immune system attacks own nerves), according to Mayo Clinic.
