Hi, I was having leg pain for past one and a half months. I was walking vigorously for 3 to 4 weeks prior to that. Haven't walked much before. Just started walking after a long gap It was like walking up and down the roads(hilly roads). So it puts so much pressure on my knees and it started hurting with some cramping and stiffness. I also have some Varicose veins in that leg. So, I thought it's paining because of the Varicose. And went to a vein clinic and had an ultrasound last month. And there was no blood clots in my veins. I was having the constant dull and burning pain in the knee and the lower leg. And fast forward to this week, I had some swelling on top of the knee for past 8 days. The swelling is the same and didn't increase and no pain. My knee hurts whenever I climb stairs. This is happening for past one month. Also I hear some popping or snapping sound from the knee and it gives a instant relief. I visited my PCP last week to check this swelling and leg stiffness along with burning pain in knee. She said it's like Patellofemoral syndrome. And told me to do some knee exercises and put on braces. But the burning pain was like throughout the day and my thigh felt so stiff. So I got an appointment with a sports medicine doctor who is also orthopedic. I saw the sports medicine doctor yesterday and they said I need an x-ray as part of the protocol. And x-ray showed that my right knee cap is moved towards right side a bit and not aligned to the center. They gave me few exercises in a sheet to follow to strengthen the muscles to keep the patella aligned. But the doctor was not sure why I have a little bit swelling on top of the knee and she touched above my knee area and said it's very hard compared to the other leg and ordered me MRI. So, she said come back after MRI. I really don't know if I need MRI. She didn't answer anything completely and wanted MRI to be done. I don't know this is how Ortho or sports medicine doctors work with this protocol in the US. I have to check the MRI imaging cost and the insurance coverage. My two concerns were the burning sensation in knee and the swelling on top of knee. But the doctor didn't answer to that. She said I have to see MRI and will see what can be done after that. And the diagnosis in the MRI order form was mentioned as beningn neoplasm of soft tissues of lower limb. I am not sure what's this. She told me that I need MRI since the area above knee is little hard and that's little swollen. There is no pain in the swollen area. Only the burning pain is there. Anyone had patella misaligned before? How did you recover from it? How long does it take to recover? Did you go to PT for? this Do we need to consult physical therapist (PT) for this? Any input is really appreciated. Is MRI necessary? Thank you for reading. Sorry for long post.
