Tingling in one hand can have a number of causes, including an injury, staying in one position for a long period of time, a circulation problem that impairs blood flow to the hands, or carpal tunnel syndrome.

Alternatively, tingling in one hand may be caused by peripheral neuropathy, a disorder in which the peripheral nerves that relay signals between the body and the brain and spinal cord do not function properly. Peripheral neuropathy can be due to a number of specific diseases and disorders, including diabetes and alcoholism. In some cases, peripheral neuropathy has no known cause.
Depending on the cause of the tingling, it may occur in your hands only or in other areas of the body as well. A tingling feeling may be the only symptom you experience or it may be accompanied by pain and numbness. The duration and course of tingling in one hand vary widely, depending on the cause. Symptoms caused by injury often have a sudden onset, whereas hand tingling resulting from underlying neuropathy develops slowly and persists or worsens over time.
Seek immediate medical care (call 911) if a sudden tingling sensation in your hand is accompanied by numbness or weakness on one side of your body; a change in level of consciousness or alertness, such as passing out or unresponsiveness; or the worst headache of your life, as these can be signs of stroke.
If your tingling in one hand is persistent or causes you concern, seek prompt medical care.
