You may be describing Raynaud's phenomenon, a condition that causes some parts of your body - such as your fingers and toes - to feel numb and change color. Although these changes usually result from exposure to cold temperatures, they can also be triggered by strong emotions or stress.

Raynaud's phenomenon is a disorder of the blood vessels in the skin. During an attack, these blood vessels narrow, which restricts blood flow to the affected areas.

The exact cause of Raynaud's phenomenon can't always be determined. In such cases, it is referred to as Raynaud's disease. But Raynaud's phenomenon can be associated with:

§ Diseases that affect blood vessels, such as atherosclerosis, scleroderma, rheumatoid arthritis and Buerger's disease (thromboangiitis obliterans)

§ Repeated trauma from vibrating tools such as a jackhammer

Treatment of Raynaud's phenomenon depends on the severity of symptoms and may include:

§ Medications to relax the walls of blood vessels

§ Avoiding cold exposure

§ Stopping smoking

Why does your hands get numb?

Not being a doctor, this answer will be from a layman's viewpoint, based on online reading of health articles. First, numbness in any extremity could be the symptoms of a very serious condition, so I strongly suggest that if you have numbness in your fingers, that you have it checked out by a doctor AS SOON AS POSSIBLE! Some of the possible causes I've read about are: 1. A blood clot blocking an artery, or 2. A mini-stroke in the brain which, I think, is technically refered to as an Intermittant Ischemic Event. Again, IF you actually have this symptom, see a doctor ASAP!!!!!j3h.
