Numbness and tingling are called paresthesia, and can occur in various parts of the body, particularly in hands, arms, feet and legs, says Healthline. Radiation therapy, seafood toxins, inadequate blood supply to the affected body part and migraine headache are possible causes of paresthesia. People with diabetes, a damaged nerve in the neck or nerve pressure may also experience paresthesia.

One of the possible diseases associated with paresthesia is multiple sclerosis, an autoimmune illness that affects the brain and spinal cord, explains Healthline. Another likely disease that causes paresthesia is encephalitis or brain inflammation. It is essential to see a healthcare professional if a person suffers paresthesia after a head, neck or back injury. Immediate medical attention is also necessary if the individual becomes immobile, loses consciousness, experiences difficulty in thinking or suffers pain.

When individuals feel numbness and tingling, they may lack sensation and may not feel pain or temperature changes in the affected area, notes Healthline. Thus, it is important to be extra cautious to prevent accidental injuries.
