I am 16, very active in sports, I have asthma, sudden stabbing pain in lower right chest. Hurts to take a deep breath, cough, or move.
Did you have any. Recent falls or tumbles? Or any upper respiratory cold? Sometimes a rib strain can cause our chest to hurt upon expiration or inspiration (breathing!) So, this could be the problem unless it's deeper involving an organ, like the liver or lower lungs. Have your doctor check it out. S/he can do a physical exam to pinpoint exactly what's going on, and help you!
