I had a herniated disc, L4/5 & used an inversion table. It made a big difference, for me. I believe you have to be very conscientious about using it. If you have high blood pressure or eye issues it may not be for you. Talk to your doctor. I inverted pretty much all the way over, but if my pain was bad I would only invert maybe 45 degrees. I still have my inversion table and use it occasionally. My herniated disc is healed - no surgery.

Be careful with them. My chiropractor advised against them. He said no more than 30 seconds but that was when I was much younger. Older people....watch out. Talk to your doctor first.

Gravity can help or hurt. It’s better to invert more often for less time than less often and for longer periods of time. The more you can relieve the pressure in your spinal column the better your circulation of cerebral spinal fluid. Which should then help relieving pain, (depending on your specific ailment.) Im not a doctor but I do work in the field of medical and fitness equipment and have worked with hundreds of people who’ve increased their quality of life by using inversion tables daily. Just like anything, it’s not for everybody and you should always be cleared by a physician before undertaking an activity like this.

The quality of the chair matters and it is good to invert only halfway or slightly more to get acclimated to the new forces on the body.

Hi @popolopo, I moved your question about inversion tables to this existing discussion:
- What are people's experience with Inversion tables? https://connect.mayoclinic.org/discussion/what-are-peoplee-experience-with-inversion-tables/

I did this so you can read previous posts and connect with others like @sequoia @mikaylar @dieslgrl @koleke and others.
