Yes, and I've found going to a chiropractor regularly (as in, 3x per week for a month, then go at least once a month after that for a while) was very helpful and totally solved my hip problems. One or two adjustments don't do enough, because the body fights back and doesn't want to be adjusted at first. I'm walking straight again, one leg is not longer than the other anymore, my hips are relaxed and move much more freely, and I just feel good. The chiropractor has also helped immensely with acid reflux, back pain, menstrual pain, hearing and vision issues, and so much more. I very rarely get sick anymore. Also, chiropractic care is SO MUCH cheaper than a PT or medical doctor. You'll get relief way faster too! (I know having someone put their hands on your body is really scary when you have fibro, but just communicate with the chiropractor and tell him/her if you can't be touched in a certain area that day. All 3 chiropractors I've ever seen have been super caring and respectful of this with me.)
In the mean time, try heating the area and stretching it as best you can. Hot baths, saunas, and heating pads are all great options. Watch your posture. When you lay on your back at night, make sure your knees are bent. I put two pillows in one pillow case and put that below my knees. When I sleep on my side, I put it between my knees. Make sure you have good lumbar support when you're sitting - poor sitting posture hurts my hips way more than my upper back.
