Raynaud’s Phenomenon
One of the more interesting causes of hand numbness is Raynaud’s phenomenon, also known as Raynaud’s disease. It’s a condition where the overall blood flow to the nose, ears, and fingers isn’t as adequate as it could be. It suffers from constriction, which is also known as vasospasm. As a result, the fingers look much paler than the rest of the body, and you experience symptoms such as hand numbness often. The fascinating thing about Raynaud’s phenomenon is it’s not usually linked to other health conditions. There are two types of the disease, known as primary and secondary Raynaud’s disease. The former is the most common and has no known causes, while the latter builds from other conditions, including frostbite and arthritis.
Raynaud’s disease is typically characterized by numbness around the hands, where the tips of your fingers start to feel cold and turn bluish due to the lack of circulation. The circulation improves when you get warm, allowing blood flow to return. That said, the condition can lead to skin ulcers or even gangrene in some of the more severe cases.
