What muscles could cause upper back right side pain?

Muscles that may contribute to upper back right side pain include Ascending part of right trapezius, Descending part of right trapezius, rhomboid major, rhomboid minor, iliocostalis thoracis, longissimus thoracis, Set of right levatores costarum breves. Trigger points, strains, or weakness in these muscles can refer pain to this area.

Q: What causes pain in the upper back right side?

Common causes of upper back right side pain include mouse arm from prolonged computer use, trigger points in the right rhomboid or trapezius, thoracic spine stiffness on the right side, carrying heavy bags on the right shoulder, muscle imbalance from dominant-side overuse. The specific cause depends on the nature of the pain, how it started, and which movements aggravate it.

Right-sided upper back pain commonly involves the right trapezius, rhomboid, or thoracic erector spinae muscles. Mouse use, carrying bags on one side, and asymmetric movement patterns often contribute to right-sided tension and strain.

Muscles in This Area

Neck

Ascending part of right trapezius

The ascending part of the right trapezius is the uppermost portion of the trapezius muscle on the right side, running from the base of the skull and upper cervical spine up toward the clavicle and shoulder. It elevates the scapula (shoulder blade) and assists in neck extension and rotation, crucial for shrugging movements and maintaining upright posture during lifts. Strong ascending traps prevent neck strain in overhead presses and rows.

Upper Back

Descending part of right trapezius

The descending part of the right trapezius fibers slope from occiput to right scapula, depressing and upwardly rotating the scapula. Essential for balanced shoulder mechanics in bilateral lifts.

Upper Back

rhomboid major

The rhomboid major is a diamond-shaped muscle between your shoulder blades, retracting the scapula for better posture. It stabilizes during rows, pull-ups, and presses, countering slouched shoulders in gym-goers. Weak rhomboids lead to rounded posture and shoulder issues.

Upper Back

rhomboid minor

The rhomboid minor, above the major, connects upper thoracic spine to the shoulder blade's inner border. It retracts and stabilizes the scapula during upper body pulls. Essential for posture correction in lifters with desk jobs.

Upper Back

iliocostalis thoracis

Iliocostalis thoracis, mid erector spinae, runs parallel to spine from low-mid back to upper ribs, aiding thoracic extension and breathing. Supports rows, pulls, and posture in upper body training.

Thoracic strainPostural myofascial pain

Upper Back

longissimus thoracis

The longest erector spinae muscle, running parallel to the spine from sacrum to mid-back, it extends the spine and maintains upright posture. Essential for deadlifts, squats, and spinal stability in powerlifting. Weakness leads to back rounding under load.
