What could cause loss of feeling in fingers?

A fellow caregiver asked...

My mother has lost feeling in her fingers. Why?

Expert Answer

Jennifer Serafin, N.P. is a registered nurse and geriatric nurse practitioner at the Jewish Homes for the Aged in San Francisco.

Loss of feeling in your fingers is usually caused by a nerve or circulation problem. The most common causes include carpal tunnel syndrome, radiculopathy, or Raynaud's syndrome (her fingers would turn blue if she had this). I recommend that she get checked out for this complaint by her health care provider to see if it can be treated, especially since numb fingers can be injured easily.
