Numbness/Tingling

If they don’t go away on their own within a few hours, numbness and tingling sensations in your hands, arms, legs, or feet can be a cause for concern.

The medical term for numbness and tingling is paresthesia. The most common reason for lingering paresthesia is a problem with nerve function, either because the nerve itself is injured, or something is pressing on the nerve.

A herniated disc or a pinched nerve in your back are good examples because they put extra pressure on the nerves in your back that run parallel to your spine, resulting in pain as well as paresthesia.

Damage to a spinal disc can create local inflammation or put pressure on surrounding nerves which can likely cause feelings of paresthesia in the hands, arms, legs, or feet.

Most causes of numbness and tingling are not dangerous to your health unless the symptoms include muscle weakness and/or muscle paralysis.  If that is the case, medical attention is advised.
