What could it be when you have a rib that is tender to touch?

Possible causes of rib tenderness:

- Bruised rib (costochondritis): This is the most common cause of rib tenderness. It can occur after a trauma to the chest, such as a fall or a car accident.

- Muscle strain or tear: A muscle strain or tear in the chest can also cause rib tenderness. This can occur from overuse of the muscles, such as during heavy lifting or sports.

- Tietze syndrome: Tietze syndrome is a condition that causes inflammation of the cartilage that connects the ribs to the breastbone. It can cause pain and tenderness in the chest, usually on one side.

- Costochondritis: Costochondritis is an inflammation of the cartilage that connects the ribs to the sternum. It can cause pain and tenderness in the chest, usually on one side.

- Slipping rib syndrome: Slipping rib syndrome occurs when a rib moves out of place and rubs against the surrounding tissue. This can cause pain and tenderness in the chest, usually on one side.

- Heart attack: In some cases, rib tenderness can be a sign of a heart attack. If you have rib tenderness along with other symptoms of a heart attack, such as chest pain, shortness of breath, or dizziness, seek medical attention immediately.
