I randomly get pain in the center of my chest and sometimes i can stretch and i swear i hear a cracking noise and it subsides. when this pan occurs it is sensitive to touch?

You may have: costochondritis, or inflammation of the cartilage connecting the rib(s) to the sternum (breastbone). Or some inflamed intercostal muscles that crack when you stretch them. Either way it is musculoskeletal and should improve with some strong anti-inflammatory medicines. Thanks for trusting in HealthTap.

Costochondral: inflammation. The cartilage that connects the sternum (breastbone) to your ribs is called the costochondral cartilage. When you stretch you pull on it, sometimes too much, the joints move, you hear a noise. The overuse can sometimes result in pain/tenderness to touch. I would not stretch so forcefully/expansively! Heavy weight lifting might also contribute. Moderation, friend. Good wishes:)

Costochodritis: an inflammation where the rib joins the sternum. Heat to the area and an anti-inflammatory should help. If not better see your doctor.
