Ya, welcome to the world of cranky back syndrome. L 2,3 and 4 are pooched. I had some of the nerves lightly burned high freq probes and go for cortizone shots every 2 months. I've been in agony since turkey day, bent and twisted to pick up a pair of boots, the "shock" was so back I almost puked up breakfast. Back to the chiro 2 times a week and sparingly taking pain killers. Good luck at your end.
