question: Hi, I am a white 33 year-old white male, 5'11" tall, 206lbs. I do swim and cardio workout once a week each. Yesterday I jumped off a fence (6-7ft high), landed on my feet. I immediately felt some pain in my back. However, today, the pain in the mid range of my back is not gone. I am able to move, but cannot bend forward because it hurts badly? what might have happened?
