Finger numbness

[cyndi66]

What could cause my index finger to be numb and tingle when touching the joint of the finger?

In addition to the numbness on the upper part of my index finger, there is just below it to the side a slight bump under the skin which is very painful to the touch.  Could I have an under the skin wart?

Many years ago I had a friend with this problem. It was caused by tight bra straps cutting into her shoulders. (Only one finger was affected). She changed her bras - bingo!

Hi, Thank you for your question. Most likely your symptoms could be due to injury to a nerve, pressure on spinal or peripheral nerves (neuropathy), vitamin deficiency, lack of blood supply due to cholesterol plaque from atherosclerosis in the extremities, viral infection and use of certain medications.  In addition, atherosclerosis can also cause pain, numbness, and tingling in extremities. They can also reduce blood supply and lead to numbness. Please consult your doctor to get all these possibilities evaluation in your case for further assessment. Hope this helps.
