Well, 6 weeks of physical therapy (and hundreds of dollars in copays) managed to do absolutely nothing for my knee, and solve even less.
So, a follow-up appointment with DoctorDoctor today resulted in a giant needle injecting some sort of steroid mix drink deep into my knee.
The pain was 90% gone almost instantly. So, when the juice runs out in 2-3 weeks, then we'll see where I'm at. If the pain is gone completely after that, then the problem resolved itself via the juice reducing unseen joint inflammation. If the pain returns after the juice wears off, then it's time for an arthroscopic, exploratory surgery.
That is all. RoboKnee sends its love.
