I am a 24 yr old, healthy and active woman. In July, I was cleaning and took quite a hard fall and hit my back on the side of the bathtub. Ever since, my thoracics and lumbar has been a problem. I have been to the chiropractor repeatedly since and the problem always seems to come back within a week. I went to my doctor and he diagnosed a muscle sprain and put me on somas, but they do not help. Also, a few weeks ago I was putting on a pair of boots and heard a snap in my very lower back...followed by alot of pain. What should I do?
