Good to hear you are seeing improvements in your situation.
When there is a long standing issue it will take time and alot of time to correct. The amount of time things remain in place following a session will increase as more returns to its proper place/positioning.
You are working to improve the situation which will not happen over night. As more items are corrected more will come into better placing/position.

If you are completing something for another look you may need to do it with another doctor if you weren’t satisfied with the evaluation from the prior time.
Is there a coach with a strong knowledge and mechanics& technique background that can look at your movement patterns with different skills?
