TKR Chronic Pain 7-8 months post

[Cullymon]

I am 34 years old with footdrop and damaged my knee being active with an AFO brace. That is the reason I got TKR at a young age. My inner side of the knee was grinding hard and I felt it everyday. Ever since I've got TKR I feel the same pain but worse, only thing better is my standing longer. My range of motion has been horrible but my doctor acts like it's a good knee just because of the X-Ray showing a healthy TKR. It's far from healthy! The incision scar is so sensitive and it's still not healed. The incision is puffy, stings, and it still easily gets blue with aches. I need to know what is going on? Does some of the pain just gradually stop like other surgeries? I want to know cause when I had orthoscopic at first it just eventually healed, that is what I thought the same for a TKR.. I need Feedback!
