On my right knee looking down at my feet just a 1/4 inch to the right of where my knee cap meets my upper thigh I seem to have a small lump when I bend my leg that gets harder as I flex my leg muscles. It causes excruciating pain doesn t feel like a cyst or anything of that nature it feels more like ligament or nerves what can I do to fix this or any ideas what is it?
In the described site usually is the head of the fibula .a lump like structure.if it is painful and tender then it might be a bursa inflamed.try anti-inflammatory ointment
