Why do I have Numbness in my Fingers?

 

 

If your fingers feel numb and tingly more often than usual, then it can indicate a problem with your nerve endings or blood flow.  Paresthesia- annoying “pins and needles” in your hands, fingertips, feet, and toes happens a lot with vitamin B12 deficiency and other conditions that affect the nervous system. Listed are some reasons that people get painful numbness in the extremities.

Why do I have Numbness in my Fingers?

Nerve damage from vitamin B12 deficiency

Painful numbness and tingling in the hands and feet are some of the first signs of peripheral neuropathy (nerve damage) caused by vitamin B12 deficiency and pernicious anemia (severely low vitamin B12). People often complain about their hands or legs constantly “going to sleep” before they even get their vitamin B12 blood levels checked.

The reason for this is that vitamin B12 is absolutely critical for a healthy nervous system, as it helps to maintain myelin, a protective coating that shields your nerve cells from harm and also enhances communication along the network of synapses.

Unchecked, vitamin B12 levels will continue to decline, leading to even worse symptoms of nerve cell damage and other debilitating ailments; depression, anxiety, chronic fatigue, brain fog, and memory problems are all conditions linked with pernicious anemia from vitamin B12 deficiency.

Pain and Numbness from Vitamin B12 Deficiency

If you experience any of the symptoms listed, then see a doctor. Ask for a blood screening for vitamin B12 deficiency. Or, start taking vitamin B12 supplements right away, and see if you notice any improvement. Vitamin B12 is safe to take in any amount, so you don’t need to worry about taking too much.

Multiple sclerosis

Multiple sclerosis (MS) is an autoimmune disorder that erodes myelin- the same substance the goes under attack with vitamin B12 deficiency. Numbness and tingling is a minor symptom of MS; for some, nerve damage impairs your ability to walk or speak without severe difficulty.

Diabetes

Diabetic neuropathy- nerve damage caused by symptoms of type 2 diabetes- is also a possible cause for constant numbness in your fingertips and toes. If it occurs, speak to your doctor. If you are diabetic, then you should be in the habit of testing your hands and legs for signs of numbness, and checking for wounds.

Carpal tunnel syndrome

If you work at a computer all day, then it’s normal for your fingers to go numb every now and then from the constant tap-tap-tapping at the keyboard. Carpal tunnel syndrome, which you get from repetitive hand motions, is a common cause of pain in the fingers, hands, and wrists. You can also get this from knitting, gaming, and playing the piano.

To treat, make a habit of taking a break every 20 minutes. If you have a hard time remembering, then set a timer to warn you when you should stop, stretch your fingers, and twirl your wrists, even for just a few minutes.

Raynaud’s phenomenon

Common in people with lupus, Raynaud’s disease causes numbness or cooling in the extremities, including the fingers, toes, nose, and ears. This happens because of inadequate blood flow to these areas.
