I knew my back was a problem, but what I didn't know, when it was not hurting, it was always weak. Dr. Cunningham operated on my spine. As I convalesced, I began to realize how strong my back had become. I could not remember ever feeling this way. What a difference! Superwoman. Dr. C is a great surgeon and gem of a person. The whole process was far less difficult than I imagined. Three cheers, Doc.
