PFPS and patella alta. Back to normal?

Hi, I have been dealing with knee burning happen and seeing from last September. Been to an Ortho and had MRI. MRI says patella subluxation and patella alta. Started PT. Going to PT from last November. No improvement in my symptoms. I still have the burning pain above the knee and swelling. PT told me to see a sports medicine doctor. I saw him. He said it's functional and my patella is high. He said, Only PT can help and prescribed diclofenac sodium 75mg for inflammation. He said there's Inflammation and that could be the reason for this swelling. I am going to same pt now. The current treatment plan is for 4-6 weeks. Going twice a week. I also got shoulder, elbow and wrist pain recently. Doctor said it might tennis elbow or shoulder bursitis or mild carpel tunnel. But pt says it's because of tight trapezius muscle. She want to try dry needling for that. How long does it take to recover from PFPS? Is it normal to have pain for so long? what to do to get back to normal? please help.
