Apparently malignancy has been ruled out. The pain drops him to his knees. He had pneumonia twice before the pleurisy diagnosis, and leads an unusually healthy lifestyle (extreme fitness training; eats chicken, fish, fresh fruits and veggies, only organic food, no soda, no junk). As a caution, and because of the lengthy illness and apparently weakened immune system, the doctor did and HIV test. Negative result.
He had a diagphramatic hernia repair as a ten year old child. It went misdiagnosed for ten years, causing him severe pain on a daily basis that entire time.
