I am glad this thread popped up. My hips have gone up 2 inches in the last couple months. I am 37 yrs 5'10" and 183 lbs I have put on 20 lbs since starting hrt. Mostly in my chest and but. So most of the growth is probably fat. But, for a month now, my hip bones have been hurting. First it was just the outer tips of the bone, then the whole bone. Just a dull ache, like a bruise. Could that just be muscles and ligaments changing?
