I am diagnosed with PFPS and patella alta. It's been 4 and a half months.going to PT for past 3 months. No improvement yet.still have the same burning pain above knee and swelling. How long does it take to recover from this? What else to do to heal from this burning pain? I also have some burning pain in my forearm, elbow,wrist recently. Been there for a month. So, my doctor told me to check Iron,ferritin,ANA,CRP,SR,RA,uric acid. All were negative.so, what could be the reason for this burning pain? The knee burning pain started in the last August and it's still the same. It gives me burning pain whenever I sit down on a chair(my knees bent) and while  lying down. It doesn't give burning pain while walking. What to do for this pain to go away? Please help. What type of treatment is required?
