Customer:

Numbness and tingling only in the tip of the finger for past 2 days. I am 63 years old.

Ken :

I can understand your anxiety.

Ken :

Let me explain a bit

Ken :

Numbness indicates that there is irritation of the nerve concerned {at the spine level or at its course}.

Ken :

The spine consists of vertebrae and intervertbral discs { soft tissue cushion if I may say }. The cord or bunch of nerves in simple word passes through the spinal canal { formed by vertebral body in front and ring like posterior part around }. Any bone spur of displacement or bulge of the disc cause pressure over the cord which results in symptoms like pain / numbness / tingling due to nerve irritation. The nerves leave the spinal canal through small rounded openings laterally. Pinching of these nerve roots can occur at this level too.

Ken :

Irritation at the course can occur secondary to diabetes/ vitamin deficiency/ excess alcohol intake, extra.

Ken :

Other cause of numbness can be reduced blood flow. It is generally associated with change in color of the finger.

Ken :

Reduced blood flow can be due to atherosclerosis, thrombosis or spasm.

Ken :

In your case my first bet will be irritation of the nerve.

Ken :

Next step -

Ken :

A physical evaluation along with few investigations like -

Ken :

MRI cervical spine, nerve conduction study/ blood tests/ color doppler for upper limb arteries if needed later will give us a clue to diagnosis.

Ken :

Till then - avoid trauma to the numb finger/ avoid jerks to the neck, avoid sitting for long on the computer/ avoid sleeping on hard floor/ avoid pushing or pulling.

Ken :

Please do not worry, you will be fine soon. God bless
