A member asked:

Can a cold sore cause extreme fatigue and swollen lymph nodes?

A doctor has provided 1 answer
Dr. Michael Thompson answered

Specializes in Hematology and Oncology

Cause/Effect: It is likely that an illness -- such as a viral illness is causing the cold sore, fatigue, and swollen lymph nodes. So the cold sore is an effect not a cause. If it persists or worsens, see your physician.
