I had a dear friend who had shingles on his chest,diagnosed by his doctor and got some RX. The pain of the shingles got very bad but he was a typical male that decided to tough it out as he hated to go to the doctor more often than he thought necessary.He tried everything his friends suggested. Finally after several months the pain was more than he could bear, the medicine no longer helped and he went back to the MD. He had developed cancer in his chest while he had the shingles. They weren't related just happened at the same time, but he waited too late to treat the cancer.
His wife buried him. He really hated to go to see a doctor.
