Question for those who have already lost a lot

I don't mean to sound like I am complainng because I am not! But after losing 155 pounds in the past year, I have 2 problems. I am cold all the time, and when I sit on anything hard (like a tub or a wooden chair) the bones in my hips dig into my posterior and it hurts like crazy. As I said, I don't want the weight back just be warm and cushioned but I just wondered if either problem will go away in time.
