Q. My fingers and toes started tingling unpleasantly about three months ago. My internist recently did blood work and found no diabetes or other abnormalities.
When the nurse asked me if I was still taking my usual medicines and vitamins, she mentioned B12. It dawned on me then that I had discontinued it when I was suffering from a nasty coughing spell. The tingliness began about the time I stopped taking the vitamin B12.
The doctor wanted to refer me to a neurologist, but I asked if I could delay that until I began taking B12 again to see if the tingling disappears. I’ve just begun, but it seems to be working. Others might like to know about this.
A. Tingling or numbness in the hands or feet is called “peripheral neuropathy.” It is a fairly common complication of diabetes, and can also be caused by some medications, including certain cholesterol-lowering drugs, cancer treatments or antimicrobials.
Inadequate vitamin B12 can also contribute to neuropathy. We hope that returning to your regular vitamin regimen will relieve the tingling. If not, please check back with your doctor.
