Have you told the dr/s, have they investigated/ re imaged?
It might be scar tissue, might be secondary injury/failure or something else..
If dr doesn't do a hands on evaluation, and if they don't want to redo images...
ask for PT referral for eval,

You might look into low level laser therapy, also called cold laser or soft laser..
If it is just soft tissue pain or a bit of internal scarring causing pain that might help.

Chiropractors seem to be utilizing the lasers the most, but you might find a PT place that has them. Make sure it is a real laser and not LED light device..they can look similar but Laser treatment is faster & better..
