Hello, welcome to Justanswer, I will try to assist you with your medical question, and any medical information you seek
What question about this wouls you like me to answer?
Is there any swelling or redness?
Any pain with weight bearing?
Do you have any medical conditions or take any medication?
Does it hurt to bend your knee?
I see, this may be due to prepatelar bursitis , which is inflammation of one of the cushions around your knee
It may require anti-inflammatory drugs and antibiotics, and it needs to be examined as well
