I also have this disease. I am 32 yrs old. I have found that hot yoga is amazing!!! It helps relieve the stiffness and tightness in my hips. In fact, I liked it so much, I decided to get certified and become a teacher. They are hour long classes. I would suggest doing it at least ever other day.
A side note: I don't know if you have a weight issue but I have found that the less fat I carry on my body, the better I feel.
Good luck!
