BAD hip pain!!!
I have had hip pain on and off. It seems to get better when I stall on my weight loss, which is when your body is adjusting to the weight loss. I was told that your body needs to adjust to carrying your weight differently. You had a different balance of weight on your hips before and now your bones and muscles need to adjust to less weight. The fact that you have lost weight so quickly doesn't help your body to adjust as fast as you would like.
I was told that it is normal, but it sure hurts a lot sometimes.
