Numbness in Fingers - Causes
There are many causes of numbness in fingers, which are mostly due to neuropathy or restricted blood flow. Given below is a list of causes of numbness in fingers:

• Carpal tunnel syndrome is a condition wherein there is pinching of the nerve present between the radius and ulna. The medial nerve gets compressed due to which, the sensation in the fingers is considerably reduced, leading to numbness in fingers.
• Radiculopathy is a condition where there is a compression of a nerve in the spine, due to which there is reduced sensation in the peripherals. It can occur anywhere along the spine, but cervical radiculopathy is a condition where the nerves emanating from in between the cervical vertebrae get compressed, leading to numbness in fingers.
• Leprosy is a condition where the bacteria enter the cells and lodge themselves there, leading to physical deformities and numbness and tingling in fingers. It is a condition that is mostly seen in third world countries.
• Thoracic outlet syndrome is a condition wherein there is compression of the nerves, blood vessels or both during their exit from the thoracic outlet, that is the base of the neck to the arm. Due to this, there is numbness in fingertips and other extremities.
• Frostbite could be a cause of numbness in hands. In extreme cold, there is constriction of blood vessels, to such an extent that the blood supply is nearly completely cut off in the peripherals. The initial symptom of frostbite is numbness in fingers, pain and burning sensation due to the decreased blood supply, but eventually, there is complete loss of sensation in the fingers, if it is not treated immediately.
• Peripheral vascular disease occurs mostly due to atherosclerosis, that is, when hard cholesterol deposits occur on the inner arterial wall. It leads to restricted blood supply to the extremities. When the arteries involved become partially or completely blocked, then it is known as peripheral artery disease.
• Diabetic neuropathy is a condition where there is nerve damage, and it is seen in advanced stages of uncontrolled diabetes. In this condition, there is numbness in fingers and tingling sensation as well, while some patients complain of pain in foot, which can eventually transgress into diabetic foot.
• Constriction of blood vessels of fingers and toes leads to a condition called Raynaud's syndrome. It leads to blanching or whitening in fingers, which is accompanied by numbness in fingers.
• Arthritis in fingers is also a reason for the numbing sensation in fingers. In fact, it is followed by pain in the fingers' joints.

The treatment of numbness in fingers will depend upon the underlying condition. In case of severe diabetes symptoms, the person should immediately try to bring down his blood sugar and cholesterol levels. For other cases of nerve compression in the spine or peripheries, it is best to consult a doctor who will be able to help you out, either with exercises or physical therapy, though in severe cases of numbness in fingers, surgery may also be required.
