I had my injection done back in November but my Orthopedic doctor didn't even think it would work and didn't use ultrasound to do the injection. It took awhile but it helped with the pain I'm thinking of getting another one since I do have some discomfort at night still not exactly pain but more like soreness. I think I need another one because I had a fall on that hip 4 years ago plus my right hip has bursitis too but not as bad as my left hip. I'd highly recommend it to anyone. My pain was 0 after the injection for about three weeks than it came back worse for another three weeks than after that it slowly got better
