@popolopo - I also had this when pregnant, like @contentandwell. It was so bad I went from waking up one day and feeling like my body was off, to holding onto walls at work, since the pain got so bad I could hardly walk by the end of the day. I was on medical leave for a month, using crutches, a walker, and a scooter at the grocery store. My doctor was very conservative with me due to my pregnancy, and I did a lot of icing, exercise and rest. I did learn that a physiatrist (Physical Medicine and Rehabilitation) could do a shot for my pain, but it was about 4 days before my induction was scheduled, so I opted to wait to see if delivering the baby helped with the pain. It completely alleviated it.
