Have you ever experienced this? I have a problem with my hip joint, it's been clicking and causing sharp pain when changing body position. Sitting or lying down is impossible, even after two months since childbirth. If you've had this issue, what caused it and how do you treat it? I was thinking about getting an X-ray but can I get one while breastfeeding?
