Hi, thanks for writing to HCM. As per your symptoms , I suspect Lumbar disc disease in you. Propably a protruded disc might be causing pressure over the nerve root producing pain down the leg. An MRI scan is mandatory to diagnose the problem. In the meantime follow these measures - * avoid lifting heavy weights as it imparts more strain on your back * avoid forward bending activities as it will worsen the disc protrusion * Use a lumbosacral back support to augment your spinal muscles * Intermittent pelvic traction to cause a regression of disc * Maintain optimum body weight,if you are obese * Physiotherapy to strengthen your back muscles. Physiotherapy has to be done only after the acute pain has subsided. * Judicious use of analgesics and muscle relaxants or as advised by your treating doctor Hope this information is helpful. Good day
