Common winter illnesses include the common cold, sinusitis, bronchitis, pneumonia, influenza, and stomach bugs.

New thinking on peripheral neuropathy

Doctors are learning that neuropathy can cause many more problems than just numbness and tingling in the feet and hands. Neuropathy of the autonomic nerves to the heart or blood vessels can cause low blood pressure, perceived as chronic fatigue and faintness or dizziness.
