Question
Dr Mark,  i suffered a l1 compression fracture snowboarding after a jump/fall, ive been to chiro, and doctors, who are hesitant about giving me advice about healing time and exercises to strengthen my back, any advice would be very helpfull, both for work and play times.

Answer
i cannot tell you how long it may take for the injury to resolve. i would not seek to work my back muscles at this time, as this may interfere with healing. i would see to it that any nerve interference problem is corrected, as this will also interfere with healing.
