I had the same thing about 6 years ago. Clicking in the right hip when I walked or did leg lifts. No real pain. Then the clicking went away and was replaced by pain that comes and goes. When I stand I get sudden pain and have to shift my weight to the left side. Doctor says it is Bursitis, and that my only options are to take lots of Ibuprofen or get the cortisone shot. Getting old sucks!
