What can cause hip pain in young adults? - pain in both hips at the same time

I am a 36 years with gastric bypass had lost a few months ago and 70 pounds. Before the surgery I had some slight pain in her right hip at times, but he said the weight. Since losing weight, my hip problem was much worse. He joins in, if I try the stationary bike or on foot is not too long. You have pain in the back of the hip (area above the buttocks) and the front end near the hip to the leg. I had a stiff hip like a child, but I do not know if this is a very hip. Rheumatoid so I'm not sure it could cause this kind of pain.
