What is chest pain on the left side?
Left-sided chest pain can be caused by many things. While people often worry about heart problems, common causes include muscle strain, heartburn, costochondritis (inflammation of rib cartilage), and anxiety. Heart-related chest pain is typically described as pressure or tightness rather than sharp pain.
When NHS resources suggest seeing a GP
- Pain comes on with physical activity and stops with rest
- You have recurring left-sided chest pain
- You have risk factors for heart disease
- Pain is accompanied by breathlessness
Self-care information from NHS
- If muscular, rest and gentle stretching may help
- Note triggers and patterns to discuss with your GP
- Practice breathing exercises if anxiety-related
Common questions
Is left-sided chest pain always a heart problem?
No. Most left-sided chest pain in younger adults is caused by muscle strain, costochondritis, heartburn, or anxiety. However, heart conditions should be ruled out, especially if you have risk factors.
How do I know if chest pain is muscular?
Muscular chest pain usually worsens with movement, pressing on the area, or certain positions. It is often sharp rather than heavy, and does not typically come with sweating or nausea.
