Physiotherapy will help if you see the right person. First understand why you rotate. It is probably related to sitting (? at a computer with your right arm forward on the mouse) and when you walk you will keep the same faulty movement pattern. ie right shoulder/thorax forward
Change these things and you should improve in 2-3 weeks. See a physio that wants to change how you move and makes sense. Don't look for exercises, but anaylse how you move and change this pattern.
