I am a soldier and just received an e-mail from a health care provider who conducted a chest x-ray on me during my deployment to Iraq.  I have been given the runaround all day by my health care providers and only want some clarification on what my condition may be.  My doctor told me that there were signs of granulamatous disease that had healed indicating an old pulmonary infection.  What does this mean, and what should i tell my wife while I am waiting on an appointment?

Summarized question: What is granulomatous disease?
