Help: Twisted pelvis?

I have a "pelvic torsion." This simply means that my pelvis is twisted. These results in a variety of problems: back pain, headaches, knee pain after prolonged exercise, hip pain after exertion, neck tension… simply because my entire skeleton is displaced. It's terrible! And I've now figured it out myself, based on all the problems I've had and with a bit of luck.

I'm definitely going to see a doctor now. But maybe someone who has this (or hopefully had it) can tell me what they did, or what helps?

Thank you very much in advance! best regards
