Q: What causes pain in the center of chest?

Common causes of center of chest pain include costochondritis (inflammation of rib-sternum joints), pectoralis major strain at the sternal attachment, muscle tension from anxiety or stress, acid reflux or gerd mimicking chest wall pain, sternum bruise from direct impact. The specific cause depends on the nature of the pain, how it started, and which movements aggravate it.

Central chest pain can involve the sternal attachments of the pectoralis major, the sternum itself, and the costochondral joints. Costochondritis is a very common and benign cause of central chest pain that can be alarming because it mimics cardiac symptoms.

Muscles in This Area

Chest

pectoralis major

The massive pectoralis major covers the chest, powering arm adduction, flexion, and rotation for bench presses and push-ups. It's the prime mover for upper body pushing strength in fitness. Building it creates that powerful chest aesthetic.

Chest

Abdominal part of left pectoralis major

The abdominal part of the left pectoralis major is the lower portion of the left chest's primary pushing muscle, attaching from the sternum down to the ribs near the abdomen. It drives shoulder adduction and flexion, crucial for powerful presses like bench variations and dips. Fitness enthusiasts target it for that defined lower chest line in bodybuilding.

Chest

Abdominal part of right pectoralis major

The abdominal part of the right pectoralis major forms the lower section of the right chest's main power muscle, spanning from the sternum to the abdominal ribs. It excels in adduction and flexion for presses and flyes, key for balanced chest development. Gym-goers love it for carving out that teardrop lower chest aesthetic.

Chest

External intercostal muscle

External intercostals are thin muscles between the ribs that elevate them during inhalation, aiding deep breathing for core stability in lifts. They're vital for endurance athletes needing efficient oxygen uptake. Fitness training enhances respiratory muscle power.

Chest

Internal intercostal muscle

Internal intercostals between ribs assist expiration and stabilize chest in lifts.

Intercostal muscle strain

Chest

transversus thoracis

The transversus thoracis are thin muscle bands on the inner chest wall beneath the sternum. They compress the chest during forced exhalation and stabilize the ribs. Important for deep breathing control in fitness and core stability.
