Chest Tightness
A sensation of pressure, constriction, or heaviness in the chest, which can stem from muscular, respiratory, digestive, cardiac, or anxiety-related causes.
⚠ Seek medical attention if:
Tightness with pain radiating to arm or jaw, breathlessness, sweating, or nausea; tightness triggered by exertion and relieved by rest
Lifestyle factors
Stress or anxiety, poor posture, shallow breathing patterns, smoking, high caffeine intake
Nutritional factors
Magnesium deficiency is sometimes associated with general muscle tension, though chest tightness itself needs medical assessment rather than a nutritional fix
Possible medical causes
Asthma, panic attacks, acid reflux, costochondritis, angina, heart attack
Next steps
Call emergency services for chest tightness with any cardiac red flags; GP or professional review otherwise
