I have tried so many modalities to treat my hip pain. If I had to pick one that makes a noticeable difference, it is the Tendlite. Best to use it at least three times a day. The cat in the picture (Jessie) is 17 years old! She walks with a little bit of a limp and can't jump very well. I use the Tendlite on her leg joints and hips and tailbone area. She seems to like it and it makes it easier for her to jump up on my lap without climbing up.
