Tight or injured muscles in the lower back are often the cause and they put pressure on the spine/nerves. Pain reliever combined with a few minutes on an inversion table helps mine. Relaxing in just the right position in the right recliner helps too (not quite fetal) with and adult beverage helps too. Also a lot of sex helps (orgasm relaxes the lower back muscles) if you can find a somewhat comfortable way to do it. Tell wife it is more effective than massaging your back and it is doctor's orders.
