Once I was on a high enough dose (extended release 3 times daily) I had relief within days, but it began to fade after a few months, then I had a terrible Crohn's disease flare and ended up in the hospital. I had not previously had this disease and the GI dr says the Indocin triggered it. Now I am back to horrible pain daily and can never take any anti-inflammatory drugs again.
Good luck. More research really needs to be done into finding another treatment for this terrible disorder.
