Sharp and tender feeling in left side of rib, feels swollen, might be bruised? when i take a deep breath, it hurts alot.

Chest pain: This may be intercostal muscle pain. A frustrating, non-serious sharp chest pain. Usually with deep breath , or cough. Indomethacin is good for this. It hurts a lot because these muscles have a linning, called pleura, on the inside of muscle that have sensitive nerves which produces this type of pain. Having said this, if in doubt always see a doctor.
