Almost everyone has felt a passing tingling or numbness in their hands or fingers. Usually, this happens when a limb falls asleep, a phenomenon known medically as transient paresthesia. However, sometimes these sensations are due to diseases, infections, or other medical problems of varying severity. A simple way to determine if the cause is serious is to rub the arms, hands, and fingers. It's unlikely that there's an underlying problem if symptoms improve. If they persist, there may be damage, irritation, or compression of the nerves.


1. Raynaud's Disease

Raynaud's disease can affect people who live in colder climates or who have other risk factors. Essentially, the smaller arteries that supply blood to the skin narrow, leading to reduced circulation until the fingers, hands, feet or toes warm up. This has a range of effects, though the most common is tingling or numbness in the hands or feet. Usually, the condition isn't medically serious, though it can affect quality of life. Individuals with Raynaud's disease may also notice that their fingers change color from white to blue to red when exposed to cold. Some people with Raynaud's have another underlying health problem such as an autoimmune disease that triggers these symptoms.
