Greetings. I had minor swelling in my knee for the last 3 years Which fades away by taking naprosyn medicine for 3-4 days regularly, I had done x ray and then it was ruled out as fabella syndrome.i don't know it was the reason for swelling, the doctor said it can be the reason. But I was not satisfied,so I did an MRI, which ruled out to be osteoid osteoma or chronic osteomyelitis. The doctor said it is likely to be osteoid osteoma. At present my knee swells when I use stairs and drive a car, so I took naprosyn medicine. I want to avoid surgery So please I request the respected doctors to give your valuable suggestions Please check attachment. Thank you
