I woke up this morning with extreme lower left lung pain. It is very painful to breathe, talk,  or laugh. It hurts a little when I touch the area. I am only fourteen, not pregnant, and dont smoke. The other day I pulled weeds for a bit, nothing to strenuous. What is wrong with me?
Your pain seems to be muscular origin, some abnormal postures or bending, sudden lifting of heavy weights can cause this type of pain, no need to worry, pain aggravates with breathing, talking or laughing is mostly muscle pain, because these actions require action of muscle if that muscle got inflamed it will cause pain.
