re: Anyone here use an inversion table for back pain?

Everyone's success story will be different. Nerve pain is so unique to each case.
Moat people incorrectly use the inversiin table and just go straight to a vertical flip. 30-40% Incline is best. It's not a game changer but works well for me in between chiro visits.
But if the injury is fresh I would see a reputable chiro after an mri and take it from there.
