Have been chasing this condition I have for almost eight years now. In the last 4 weeks it has gotten a lot worse.
Chest / lung discomfort. Burning pain when exercising intensly and unable to continue for very long. Head and eyes feel like a sinus infection without the infection mucus. This eye feeling is 24 / 7. Very uncomfortable for a while after heavy exercise.
Is definately not a "heart attack" condition. Been tested a few times.
