I hope that PT stands for physical therapist and not personal trainer as it is beyond our scope to diagnose problems and prescribe exercises for it.
If you have done the exercises correctly and as often as recommended, then there should be some improvement at this point in time. If this is not the case, I would refer back to the physical therapist. Others have suggested alternatives as well but I would start with the PT and take it from there.
I hope that you will be out of pain soon.
