Mack–
Working through something can be a process.
As you get one thing back to where it should be you may see other things show up that were compensating for the first thing being out of place. Go to work on those.
Were you given a cause for the issue when it happened the first time?
Have you looked up stream and down stream of where you are seeing the issue?
When do you have the pain or restriction in movement?
Some could be tied to how you are breathing.
