[|Human|] I have what feels like a small ball shaped object on my knee cap , and when on my knee it causes severe pain. Then the other day I fell onto my knee causing this ball shaped object to pop or open under my skin now I am in excruciating pain anytime it is touched , what is this and what should I do?
[|AI|]  Hi, Thanks for your query. Well, without a clinical evaluation it would be difficult to determine the cause of the lump. Possibilities that may need to be considered include enlarged bursa, lipomas, cysts, growths from underlying connective tissue etc. I would suggest getting this evaluated by an orthopedic for an accurate diagnosis and appropriate management. You may get the X-ray of the area affected and FNAC (fine needle aspiration cytology) of lump under his/her guidance. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care
