<s>[INST] Several weeks ago, I accidentally hit my knee coming out of a bad round-off backtuck. I hit it on the floor and now there is a burning, tearing sensation on the medial side of my patella. It progressively felt better and there was only a little pain when I would put pressure on my knee and when the quad muscles were being stretched. Today, hit my knee again on a bad roundoff backhandspring and now the pain is back in the same area; there is slight swelling. My knee was flexed both times when it was hit, but there was no twisting. [/INST] Hello, As per your history, it may be due to blunt trauma. For further assessment you may require MRI knee joint after orthopedician consultation. Till then you can take tablet acetaminophen. Use support while walking. Use knee cap. Do regular physical therapy. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Shyam B. Kale, General & Family Physician </s>
