behind door number one

I had an appointment with the doctor today about my knee issues and back to physical therapy I go. (I've been in physical therapy in and out for about 4 years when i was younger). I haven't had therapy for at least 4 years. I was hoping I was completely finished with it. But on the bright side, I will hopefully be able to fix my problems as best as I can so I don't develop bigger issues as I age.
