I have tried everything for lower back pain. Here is how I would rate what is offered, from best to worst. My experience may be different (of course) than others:
-exercise, losing weight, strengthening core, stretching (esp the Mackenzie method), foam roller (all at home)
-at home TENS machine
-massages
-massage gun
-heat therapy and ointments
-chiropractor adjustments
-decompression
-cupping
-acupuncture (did nothing for me)
Good luck. Lower back pain is the worst, but I will do everything I can to avoid surgery. I have heard of so few good outcomes after lower back surgery.
