If the pain in the heart area only occurs during inhalation, it should be caused by intercostal muscle or intercostal neuralgia, not necessarily caused by heart problems. If this pain is serious, you can use painkillers to relieve it first, and usually pay attention to do more stretching and chest expansion exercises to help prevent and improve this pain. This pain is usually related to factors such as low exercise, prolonged use of computers or cell phones, etc. To avoid this condition, you should avoid these factors that can cause intercostal muscle or intercostal neuralgia in general. If you are afraid of heart problems, especially for patients with high blood pressure or diabetes who have pain in the heart area, you can have an electrocardiogram to rule out heart problems.
