I am having recurring pain in the right side of my chest. It is usually when I am under extreme stress. A knot forms to the right of my stearum. Sometimes it takes several minutes for it to go away.

Hello. Thank you for writing.

Chest pain on the left side is typically associated with a heart attack. But that doesn't mean chest pain on the right side (or chest pain in general) shouldn't be evaluated by a doctor. Extreme stress can bring on panic attacks, which can feel very similar to a heart attack. Panic attacks can happen out of the blue or be triggered by a traumatic or stressful event.
Stress and panic attacks can cause chest pain because when you hyperventilate, tense or tighten up, your chest wall muscles can spasm. This pain can occur on either side of the chest.  If your doctor feels this is the case, stress management can help.
