Hi! No, it does not snap or feel out of place, but when physical therapists examine my pelvis they say it is out of alignment. My main symptoms are butt pain, and some tailbone pain. I used to have a small amount of butt pain on just one side and just when sitting, now it is on both sides, and the last several weeks it is bi-lateral and I get it when standing in one place also. I am going back to try Physical Therapy again. I will post on my progress in the next few weeks. I think SI Joint problems are often misdiagnosed as low back problems, and I am surprised not to have found a discussion of SI Joint issues on this forum.
