Facet Joint Sprain

Hi there. I am a week into the structured program with good results and today for some reason I started doubting the TMS diagnosis. Last time I saw the doctor, he said he thinks I may have sprained a facet joint and that is causing my pain. I don't remember any trauma. He saw fluid around the joint on an MRI. I also had a bulge and a disc tear. I have been having back pain since October. I am not sure if anyone has experience with facet joints? Could this be TMS? Is sounds like an accute injury but I have been having pain for many months. I also have had a long pain history.
Also, what do you do when you slip up and start to doubt. I feel like I need to start over.

 

I don't know about facet joints but I do understand about doubt. I wish I could get rid of my doubts. Have you been to see a TMS doctor? I have an appointment in March and I'm hoping that will help put and end to doubt.
