I used to have problems on my butts and on my back and hip areas too. I tried everything it didn't help much.
There were three things that helped me most.
1. Celebrex. But the pain started coming back.
2. Myotherapy. Learn about this therapy, it does work.
3. Calcium supplement. In particular I tried Coral Calcium (won't give the brand name), & it has helped me tremendously. I hardly have any pain now. You can see my other postings, to know the particulars of my pain.
Hope that helps.
