5.Heartburn
If acids from your stomach go up into your esophagus, you can feel pain not only in your chest, but in your jaw and throat as well. Alcohol, smoking, aspirin and other noninflammatory drugs, and citrus fruit can all be triggers. So can eating too close to bedtime. Call your doctor if you burp and don’t feel better, or you have other symptoms like nausea or sweating.
6.Muscle Pain
Being more active or exercising harder than normal can strain the muscles in your chest wall. You may notice that your pain is worse when you’re sitting or standing a certain way. Taking a deep breath or pressing on the sore area might hurt. Scale back your workout and don’t lift heavy things until the pain gets better. A heating pad or ice pack on the area can help. Esophageal spasms are a common cause of chest pain, so be aware of your symptoms..
