I suffered back pain from the age of 18 until I was 41. No major structural damage, a couple of bulging discs, muscle spasms, and nerve pain, debilitating at times and going out on a boat would mess me up for weeks. I bought a book called whartons back book, and started doing the stretches in it, after a month or two my back got a lot better, started running and doing weights again no back trouble for the last three years. Stretching the hamstrings, quads, hip abductors and adductors, psoas, groin and glutes ( all the muscles through the upper legs, pelvis and lower back) has worked wonders for me. If I feel pain coming on I get straight into the stretches. Losing a few kgs and stretching are a must provided you haven't got major structural damage
