How is the little finger and ring finger of the right hand suddenly numb?

After the phone call, you feel numb in your little finger, ring finger and half of your palm, which is caused by the compression of ulnar nerve in your elbow. If numbness occurs frequently, it is the manifestation of cubital tunnel syndrome.

The ulnar nerve communicates with the ulnar nerve at the elbow. When I was on the phone, my elbow was propped on the table, which made the ulnar god get stuck. After a long time, I became numb.

In addition, cervical spondylosis, cubitus valgus and osteoarthritis of elbow joint are common causes of ulnar nerve compression.

If the above symptoms occur occasionally, most of them have no pathological significance. If necessary, go to the hospital to do relevant examinations, such as ulnar nerve examination of elbow and cervical radiography, to make a clear diagnosis.
