Okay, so I went to see Dr. Borden and he reported that my MRI looks normal. For this I had to schedule an appointment, drive to Canton and back, pay $15 and let him bill my insurance. He has no idea what's wrong with my knee. But the good news is, I don't have a ligament tear. Probable something's wrong with my soft tissues, like muscle or tendon.
This doesn't surprise me much, since I originally thought it was pulled tendons. I asked if he thought physical therapy would help. He was unsure how much it would help without an identified problem, but he wrote me a prescription anyway.
