Hi, i am an 19year old female. Very active athlete (runner) and cyclist. For the past year i have been experiencing very bad knee pain whilst walking for long periods of time. If i am walking for more than 10-15minutes, i begin to get an aching pain with in my knee behind my patella. This pain leads to the feeling of something being placed within my joint like a wooden block that restricts me from straightening my leg. As i straighten my knee i can feel the lump deep inside the joint. Along with this i have begun to experience strange episodes of my joint swelling, numbing, stinging and going extremely red and hot. This only last for minutes but it seems to happen on both joints regularly. I have been on Prednisilone (steroids) for over 15 years now. I have no idea what is causing this pain
Can anyone help??
