Patella femoral pain syndrome for 4 yrs.

It started as knee pain, leg pain, ankle pain in 2019 and saw some swelling in the knee. Right knee. I also have varicose veins in that leg behind the calf. So went to Dr and got tablets for it. But knee pain didn't reduce. Then went to Ortho Dr and took x-ray. He said patella moved a little. And sent for MRI. MRI shows PFPS and Dr sent me for physical therapy. I did lots of physical therapy and pandemic started. Didn't go back to PT. Knee pain is still there and hurts if I walk or stand for a while. I hear sound like cracking knuckles sound inside the knee. Always pop and crack. Went back to Dr last month. Took another x-ray. He said patella is not moved back to normal position and still laterally moved. He told me to continue the exercises and gave one ointment. My knee just burns if I stretch it straight. It burns in the right side of knee. Lateral.Burning pain in knee since 2019. Doing exercises like lifting knee by stretching the leg. No changes. Will this get back to normal?
