Hip injections have really helped me. I have one of the autoimmune forms of arthritis, and my hips are the only area that continues to hurt despite aggressive treatment.

The injections I've had were done by my rheumatologist who is also board certified in pain management (yay!). They're done at the hospital or an outpatient facility under fluoroscopy (live x-ray). I've never been sedated for them, but it is an option with some doctors. I got 6-8 months out of one and about a year out of another. Your mileage might vary.

I've also done PT to help. Because of the pain, I've limped a good bit over the last 5 years or so, and my musculature has changed. PT helped balance me back out and get my gait back to normal.

Also, if you haven't had a pro bike fit and talked about the hip issues, I'd suggest getting one done. I sit pretty high on my bike according to just about everyone who sees me on it, but it makes my hip happy.
