A tingling sensation in the arms may disrupt a person's normal activities and be painful. This sensation is called paresthesia and may be the result of many medical conditions, diseases and disorders. Paresthesias may last for a few minutes or over a long period of time, depending on the cause. Medical care is always advised to rule out any serious medical condition.
Herniated Disk
Disks are found in between the vertebrae of the spinal column; they allow the back to bend in different directions. When a person has a "slipped" or herniated disk, the inner part of the disk protrudes outward and puts pressure on the nerves. According to the American Academy of Orthopaedic Surgeons, a herniated disk in the neck can cause tingling or numbness in one arm, weakness in an arm, loss of control over bladder or bowel functions, and a burning sensation in the shoulders, neck or arm. Treatment includes rest, ice and muscle relaxants. Surgery may be considered if loss of function is significant.
Carpal Tunnel
The carpal tunnel is located on the inside of the wrist and protects the main nerve to the fingers and the tendons that allow the fingers to move. Pressure that is put on the carpal tunnel can cause tingling and numbness in the hands, arms and fingers. Other signs and symptoms reported by MayoClinic.com include weakness in the hand and pain from the shoulder down to the palm and fingers. Treatment may include nonsteroidal antiinflammatory drugs to alleviate pain and swelling, cortisone injections and putting the wrist in a splint at night. Surgery may be needed if the pain continues for over six months.
Peripheral Neuropathy
Peripheral neuropathy occurs when the peripheral nervous system is damaged. The peripheral nervous system is responsible for sending information from the brain and spinal cord to the rest of the body. When damage occurs, the information can become interrupted. According to the National Institute of Neurological Disorders and Stroke, signs and symptoms can vary greatly. These include a tingling sensation or numbness in the arms and legs, insensitivity to touch, muscle weakness, organ dysfunction and paralysis. Peripheral neuropathy may be caused by trauma, diseases that are either acquired or inherited, infections or autoimmune diseases. Peripheral neuropathy has no cure, and treatment is based on the cause of the condition.
