### Patient: Doctor, I have been having some knee pain and ankle pain lately, and I have noticed a lump on my knee. What could be the problem?
### Doctor: Based on your symptoms, it is possible that you may have Sporotrichosis. It is a fungal infection that can lead to the formation of lumps on the skin. It is common in people who handle roses, soil or moss. I recommend you get some tests done to confirm the diagnosis.
