Sorry that you two are going through such a rough time. I agree that you shouldn't go back to any PT that says your son is lazy...there is no reason a physical therapist should ever make a patient feel that way when they are dealing with an incredible amount of pain like this. He needs support from the people trying to help him...it's the only way he will make progress. You have been doing as much as possible for him and no doubt the only progress he has made has been because of you.

I hope you can find a dr and physical therapist who will be able to help. Even if options are limited...they won't do any good if he doesn't have the right support from the medical side. He CAN and WILL get better...don't give up hope. I understand the frustration both you and he have got to be feeling and it's okay to feel that way. I found some of the best things happened to me treatment wise when I felt like I was at the end of the line with one dr and ended up with another. The right dr for one person is not necessarily right for another and treatment plans cannot be one size fits all. You'll find the right fit for your son...keep him doing what is helping and though progress may seem painfully slow it's just important that he keep moving forward (don't get discouraged by small setbacks) and don't rush to force progress on someone else's timeline.

You will both get through this.
