Chest pain dull, not major, more uncomfortable with deep breath or movement?

Chest pain: If otherwise healthy, then it may be a simple costochondritis (inflammation of the joints where the ribs meet the breastbone). This improves slowly with time. But, if you have been ill recently (like with a cold), it could be something more serious related to your heart or lungs, and you should go have it checked. If feeling otherwise well, use ibuprofen to help with the pain.
