Hello,
I recently went to a doctor because I have a strange lump in my knee.
It never caused me any problems, but after a year I thought I should go just in case.
For the year I had the lump, I experienced no pain or even the slightest discomfort.
The lump appeared one day in my knee. I sat down in an odd way and a sharp pain ran through my knee. The pain did not go away the whole day, so I eventually pushed really hard on the back of my knee and something popped out and floated to the top of my knee from the bottom. I have had a hard lump ever since. When I went to a doctor, I got an X-ray. He confirmed that it was a piece of bone, and he believed it fell off from the bottom of my bone. He thought there was a chance it was osteochondritis dissecans. I went to get an MRI two days ago, and I have the images, however my doctor has not called me back. I would like to know if I have osteochondritis dissecans, or if it is something else. I would also like to know what I should do and if I should be worried. I am a sixteen year old female who runs track all year round. Thanks very much. Attached is one image from my MRI that has me a little worried.
