Tingling in Hands and Feet.
In many cases, however, tingling in the hands, feet, or both can be severe, episodic, or chronic. It also can accompany other symptoms. such as pain, itching, numbness, and muscle wasting. In such cases, tingling may be a sign of nerve damage, which can result from causes as varied as traumatic injuries or repetitive stress injuries, bacterial or viral infections, toxic exposures, and systemic diseases such as diabetes.
Such nerve damage is known as peripheral neuropathy because it affects nerves distant from the brain and spinal cord, often in the hands and feet. There are more than 100 different types of peripheral neuropathy. Over time, peripheral neuropathy can worsen, resulting in decreased mobility and even disability. More than 20 million Americans, most of them older adults, are estimated to have peripheral neuropathy.
It's important to seek prompt medical evaluation for any persistent tingling in your hands, feet, or both. The earlier the underlying cause of your tingling is identified and brought under control, the less likely you are to suffer potentially lifelong consequences.
Causes of Tingling in the Hands and Feet
Diabetes is one of the most common causes of peripheral neuropathy, accounting for about 30% of cases. In diabetic neuropathy, tingling and other symptoms often first develop in both feet and go up the legs, followed by tingling and other symptoms that affect both hands and go up the arms. About two-thirds of people with diabetes have mild to severe forms of nerve damage. In many cases, these symptoms are the first signs of diabetes.
In another 30% of peripheral neuropathy cases, the cause is unknown or 'idiopathic.'
The remaining 40% of cases have a variety of causes such as:
Nerve entrapment syndromes. These include carpal tunnel syndrome, ulnar nerve palsy, peroneal nerve palsy, and radial nerve palsy.
Systemic diseases. These include kidney disorders, liver disease, vascular damage and blood diseases, amyloidosis, connective tissue disorders and chronic inflammation, hormonal imbalances (including hypothyroidism), and cancers and benign tumors that impinge on nerves.
Vitamin deficiencies. Vitamins E, B1, B6, B12, and niacin are essential for healthy nerve function. A B12 deficiency, for example, can lead to pernicious anemia, an important cause of peripheral neuropathy. But too much B6 also can cause tingling in the hands and feet.
Alcoholism. Alcoholics are more likely to have a thiamine or other important vitamin deficiencies because of poor dietary habits, a common cause of peripheral neuropathy. It's also possible that alcoholism itself can cause nerve damage, a condition that some researchers call alcoholic neuropathy.
Toxins. These include heavy metals such as lead, arsenic, mercury, and thallium, and some industrial and environmental chemicals. They also include certain medications - especially chemotherapy drugs used for lung cancer - but also some antiviral and antibiotic drugs.

Infections. These include Lyme disease, shingles (varicella-zoster), cytomegalovirus, Epstein-Barr, herpes simplex, and HIV/AIDS.
Autoimmune diseases. These include chronic inflammatory demyelinating polyneuropathy, Guillain-Barre syndrome, lupus, and rheumatoid arthritis.
Inherited disorders. These include a group which may have sensory and motor symptoms, the most common type is known as Charcot-Marie-Tooth disease.
Injury. Often related to trauma, nerves can be compressed, crushed, or damaged, resulting in nerve pain. Examples include nerve compression caused by a herniated disc or dislocated bone.
