The pain is intermittent, and poorly localized, but has been increasing in severity. He has also experienced frequent episodes of coughing that sometimes produce bright red blood. Past medical history is notable for hypertension and hypercholesterolemia. The patient works as a farmer and often walks barefoot through the fields.
