Yes! Im having the same problem and was worrying myself over it. Now I feel better knowing others are having the same problem. I have my next dr appt tomorrow and am going to bring it up. But my groin area especially on left side hurts when I get up to walk and when I turn over in bed ...feels like I have pulled a muscle. I really hope this will go away soon...I am seriously waddling because of it!
Turning over in bed is actually when I have some of the worst pain. That and walking up stairs, getting in and out of vehicles etc. My pelvis has been clicking and popping as well...always when turning over in bed. I've come to dislike going to sleep because it's almost as bad as walking around. :S
Oh, and when my pain first started, I developed a crazy waddle too. I'm still waddling but not quite so bad. I have learned to fix my legs a certain width apart to help even my hips out etc. I bet it looks funny though.
