Abdomen
Side of Abdomen
Pain on the side of the abdomen typically involves the oblique muscles, the serratus anterior, or the lateral intercostals. Side stitches during exercise, oblique strains from rotation, and rib stress injuries are common muscular causes.

Common Causes
Side stitch (exercise-related transient abdominal pain)
Oblique muscle strain from twisting or rotation

Rib stress fracture in athletes
Muscles in This Area
5Abdomen
external oblique
External obliques form the outer 'V' of your abs on each side, rotating and side-bending the torso while compressing the abdomen. They're powerhouse muscles for rotational power in sports like golf, boxing, and throws. Train them for a defined waist and core stability.
Chest
serratus anterior
Serratus anterior wraps from ribs to scapula, protracting and upwardly rotating the shoulder blade for punches and presses. 'Boxer's muscle' prevents winging, crucial for overhead athletes.
Abdomen
Diaphragm
The diaphragm is the dome-shaped breathing muscle separating chest from abdomen, contracting to inhale. Central tendon anchors it, essential for core bracing in lifts and endurance.
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.

When to See a Doctor
Seek medical attention if side pain is persistent and not related to exercise, accompanied by blood in the urine (possible kidney issue), radiates to the back or groin, or is severe and sudden.
Self-Care Tips
Gently stretch the obliques with standing side bends
Warm up properly before exercise to prevent side stitches
Rest from rotational exercises if the oblique is strained
Apply ice to an acute strain and heat to chronic tightness
