I am a 24 year old female who has had inconsistent chest pain for over a month. The chest pain occurs daily (usually sharp but not unbearable in the center slightly on the left side). The chest pain is usually sharp, but only lasts a few seconds. Sometimes it occurs only a few times a day, others every half hour or so. I have visited the doctor and my blood work, EKG, and chest X-ray all came out normal to much relief. The pain is usually alleviated somewhat and occurs less frequently while taking naproxen. I have never had this kind of pain before. What could be causing it? A pinched nerve? My food habits have not changed and I do not believe it is a digestive problem nor congestion (doctor listened to my heart and lungs as well).
