Can poor posture cause chest pain?

Yes. Rounded shoulders and forward head posture strain the thoracic spine and tighten chest muscles, producing pain in both the upper back and front of the chest (thoracic outlet-type symptoms).

Important Disclaimer

Overview

The thoracic spine and chest wall share musculoskeletal structures and innervation. Most combined upper back and chest pain is musculoskeletal (poor posture, thoracic disc issues) or GI-related (GERD). However, cardiac causes must be excluded in at-risk individuals.

Possible Causes

Thoracic Muscle Strain

common

Overuse or poor posture straining rhomboid and trapezius muscles produces both upper back and referred anterior chest pain.

GERD

common

Acid reflux causes burning chest pain that can radiate to the upper back between shoulder blades.

Cardiac Event

rare

When It Is Serious

Any combination with shortness of breath, sweating, cardiac risk factors, or sudden onset should be evaluated urgently.

When It's Likely Benign

Pain reproducible by pressing on the chest or upper back, worsened by posture, improving with stretching.
