Finger numbness can be the result of injury, cold, circulation or nerve problems in your hand and wrist. If your numbness is mild and transient, you may be able to treat it at home by warming or stretching your hand. If tingling, numbness or pain in your hands is persistent or severe, see a doctor to prevent potential complications and to relieve your symptoms.
Carpal Tunnel Syndrome
Carpal tunnel syndrome is common in people who regularly use their hands in repetitive tasks such as typing, sewing, writing or using certain tools. These types of movements can irritate the carpal tunnel, which is the channel that holds the median nerve leading to your hand, says MedlinePlus. Symptoms of carpal tunnel syndrome include numbness, tingling, pain, weakness in the hand and problems with coordination in the affected hand. Since untreated carpal tunnel syndrome can lead to permanent nerve damage, it is important to see a doctor for treatment, which may include medications, injections or, in some cases, surgery.
Tendinitis
The American Academy of Orthopaedic Surgeons describes a type of tendinitis, called De Quervain's tendinitis, which causes numbness and tingling in the thumb and index finger. The condition is caused by the thickening or inflammation of tendons around the base of the thumb, and is common during pregnancy or in patients with inflammatory arthritis. Treatment options include splints, rest, anti-inflammatory medications such as ibuprofen and steroid injections. In some cases, your doctor may need to perform surgery to alleviate your symptoms.
Raynaud's Disease
Raynaud's disease, sometimes called Raynaud's syndrome, is characterized by numbness and tingling in the fingers, toes, nose and ears. It is more common in women than in men, and more common in those living in cooler climates, explains MayoClinic.com. If you have Raynaud's disease, the blood vessels in your extremities become narrower in response to cold or stress, causing your fingers to become cold and numb. They usually turn white, then blue, then pink or red as blood circulation to the area improves. If you have a mild case of Raynaud's, you may be able to manage it at home by warming your hands to restore good circulation. If your symptoms are bothersome, see your doctor for advice.
Stroke
If your numbness actually involves the whole arm, comes on suddenly and is accompanied by confusion, severe headache, trouble walking or difficulty speaking, you may be having a stroke, says the American Heart Association. Stroke is a medical emergency, and requires immediate medical care. Call for emergency care if you or someone that you are with experiences these symptoms. Be prepared to give the doctor the time that your symptoms started.
