Hi, Brief answer: In my opinion, the sharp pain in your chest is consistent with precordial catch syndrome. However, you should consult with your doctor about chest pain so that they can better evaluate the cause of your pain and make sure it is not from your heart of lungs. Detailed answers: Chest pain can be caused by many things including heart disease, inflammation or infection of the lungs, heartburn (acid reflux), muscle cramps, and irritations to the nerves in the chest wall. Precordial chest syndrome is thought to be caused by irritation to nerves that run under the ribs. PCS causes sharp, twinges of well localized chest pain that lasts from seconds to minutes and that usually worsens when taking a deep breath, causing paints to take shallow breaths to avoid pain. However, this pain usually resolves with relaxed DEEP breathing. The experience of chest pain can cause anxiety, but be assured that the chest pain in PCS is not from lung or heart disease. I instruct my patients to take DEEP breaths as soon as the pain begins, as the pain in PCS typically resolves with relaxed deep breathing. In any case, please consult your doctor about your chest pain so that they can make sure that there is not a problem with your heart or lungs. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Aaron Shapiro, General & Family Physician
