hydrotherapy can help too. its gentle on the joints.

Also swimming...it's amazingly easy on joints, yet is exercise

I think the repetitive motion on your hips would make your bursitis worse or flare longer. If it was only Fibro I would say go for it as excercise might be painful but does not do damage to joints.
For arthritis I would try stretching, tai chi even yoga. Walking on a treadmill or just around the house avoiding stairs as an excercise because can make your bursitis worse. Google treatment and excercise for bursitis and arthritis in hips see what they recommend. Hope this helps. Gentle hugs and God bless.

I have Fybromyalgia, bursitis and arthritis in my Si joints and spine also Crhonic fatigue syndrome. I use an encumbered bike a little at a time as little as a minute sometimes but I try every day some better than others it helps to move and get some cardio.

Thankyou all for your answers this helped me from a lot of pain 💜 Hugs to all have a great hopefully pain free day!
