Numbness in Hands and Feet

Numbness in Hands and Feet

Numbness and tingling in your hands and feet can be a temporary symptom such as when you sit on your foot and it "goes to sleep" or a persistent and severe sign of a more chronic disease or injury. More severe injuries may indicate that nerve damage (also called peripheral neuropathy) has occurred. Peripheral neuropathy can be a progressive problem that can result in permanent impairment. What causes numbness in the hands and feet? What treatments are available? And how do you know when you should get in to see your doctor?

Causes of Numbness in Hands and Feet

Diabetes. Diabetic peripheral neuropathy is one of the most common causes of numbness and tingling in the hands and feet. Typically, this neuropathy starts in the feet and may be one of the first symptoms that an adult has developed diabetes. Almost one-third of all peripheral neuropathies are caused by diabetes.

Nerve Entrapment Syndromes. Numbness in the hands and feet can be caused when a nerve becomes pinched or trapped such as with Carpal Tunnel Syndrome or ulnar or radial nerve palsy. These syndromes are usually caused by repetitive actions (typing, playing a piano, carrying a heavy shoulder bag, etc.) over time. Depending on the nerve that is trapped, symptoms may start with numbness, but can quickly progress to burning or stabbing pain. In rare instances, nerve entrapment can lead to paralysis of the affected extremity.

Systemic Diseases. Diseases of the kidney, liver, connective tissues, cardiovascular system and Tumors can cause numbness in hands and feet. For example, left-sided arm numbness can occur in Angina and myocardial infarction because of inadequate oxygen supply to the heart. In this case, numbness can be a symptom of a life-threatening illness.

Vitamin Deficiencies. Deficiencies of the B vitamins and vitamin E can lead to peripheral neuropathy. All of these vitamins are critical to maintain healthy nerves, so a deficiency may show up as numbness in the hands or feet.

Alcoholism. The peripheral neuropathy common in alcoholics is usually related to the vitamin and thiamine deficiencies due to poor diets. Alcoholics can also develop nerve damage from chronic alcohol use, often referred to as alcoholic neuropathy.

Toxins. Heavy metals (for example, mercury, lead and arsenic) and other chemicals may cause peripheral neuropathies. This can also include those chemicals in the form of medications that are used to treat Cancer and viruses.

Infections. Neurological infections such as Shingles, Epstein-Barr virus, herpes, Lyme Disease, and Hiv/Aids can lead to peripheral neuropathy causing numbness in hands and feet.

Autoimmune Diseases. Autoimmune diseases in which the body starts attacking itself can also cause neuropathies. Common diseases in this category include Guillain-Barr¨¦ syndrome, rheumatoid Arthritis, and lupus.

Inherited Disorders. Charcot-Marie-Tooth neuropathy is a group of incurable inherited disorders that may result in peripheral neuropathy and loss of sensation in the hands and feet.

Injury. Nerve damage leading to numbness is often caused by trauma or some other mechanism of injury. Bone fractures or dislocations are common causes of nerve compressions that can result in numbness of hands and feet.

Anxiety. Anxiety can result in an increased respiratory rate which can result in increased oxygen to the hands and feet. This increased oxygen can result in carpal-pedal spasms and numbness of the hands or feet. Breathe slowly into a paper bag for a few minutes to relieve these symptoms.

Migraines. Many people with migraines may experience numbness in the hands and feet when a migraine is beginning. This sign may help the sufferer identify when the migraine is beginning - and may allow you time to intervene early in the Headache.

Stroke and TIA. A stroke or transient ischemic attack (TIA or "mini-stroke") may cause numbness usually on only one side of the body. Symptoms of the TIA usually go away within a few hours whereas symptoms of a stroke may never resolve. Any facial or one-sided numbness without a known cause should be evaluated immediately.

Multiple Sclerosis. Progressive nervous disorders such as multiple sclerosis (MS) cause numbness because the myelin sheath of the nerve is disrupted. Nerve impulses cannot be sent over the damaged nerve so the person with MS will often complain about numbness and Tingling In Hands and feet.
