The location of the knee pain can be a useful guide. Pain in the front portion of the knee can be caused by bursitis (inflammation of the lining of the joint, possible due to injury while playing), arthritis, or injury to the patella cartilage (front portion of the knee). Pain on either sides of the knee is usually related to meniscal tears, injuries to the collateral ligaments, and even to arthritis. You will need X-rays and MRIs of the knee to find the exact. Treatment will follow correct diagnosis. Do consult an orthopedic specialist at the earlier. Take care!
Hello, thanks for responding the pain has not gone away and it has been almost three weeks, the area of the pain feels to be a little under my knee cap in front and slightly moving to the left side of the knee cap area. When I bend it and try to put weight the pain is a instant sharp shooting pain and it looks a tiny bit puffy on the left side of the knee cap but I put ice and it don't go down. Had xrays done and I was told by ER dont look bad, should I not listen and get a MRI?
