What meds work best for Sacroiliitis?

I have sacroilitis in both SI joints. I have tried all kinds of medicine for relief. I have found that Skelaxin works best of all for me. I have also had the joints injected with a steroid-type medicine using a CT scanner. I feel like I can jump over a house for a few weeks. The pain vanishes after injection. Hope this helps! I understand the pain. In addition, physical therapy has helped to stretch the joint.
