I just returned from a camping trip. I live at sea level, camped at 7,000 feet, and hiked at almost 11,000 feet. I ve never experienced altitude sickness. Twelve hours after returning home, I woke up with pain in my chest when I breathed. The pain is concentrated around my sternum, and feels like a bruise. It begins when my lungs are halfway full, and worsens. On a scale of 1 to 10, the pain is about 3 or 4, but worsens when I lay down or bend over. I did not experience any discomfort while camping, and did not drink any unfiltered water. The pain has persisted for about 36 hours without change. Any idea what could be wrong?
