Hello Gideon. Glad to see you've successfully posted.
Do you have the MRI of your injury saved on file somewhere? or even the physical copy. Doctors will need to reference this or else they might make you take another MRI.
I recommend starting with that: get your MRI and get it analyzed, specifically, size of your defect, location of defect, and any other relevant details. Once you find these please post them here, as well as bring them to your doctor's visits.
Finally, you may want to research other users' experiences withi doctors on this forum. It's a rare injury so generally we tend to use the same small circle of doctors.
