Surgeon-Chronic Pain

Virologist Carol Duffy, left, and Tuscaloosa surgeon Dr. Skip Pridgen look at cultured cells used for growing a virus on in Duffy's lab at the University of Alabama Friday, Sept. 7, 2012. Pridgen has a theory that fibromyalgia and other gastrointestinal disorders may all be caused by the same virus that causes cold sores. His theory, which is being supported by Duffy, who studies virus replication, is likely headed for a clinical trial.
