Hang in there buddy! I know how stressful the wait is, all the best and I hope your PPR comes through soon.
After studying the GCMS notes that I received, and spending hours on them, I realized that each task has a due date. When they create an activity, they mention stuff like "Created on", "Updated on", and then there is a field called "Due Date". Now I am assuming here that this due date is the date when someone will come back and see one's application. If the necessary information that they have been waiting for has arrived, they will move the application along, otherwise probably assign a new due date. In your GCMS notes, do you see a Due date for the activity that was initiated after your medicals expiry related CSE?
