No injury to that knee but I have arthritis and a torn meniscus(sp?) in my other knee so it was my thought that I had been favoring my bad knee causing more stress on my right knee. It has been stiff for about 3 or 4 days now. No back pain but my hips are a bit stiff as well. No pain down my leg just up the outside of my thigh like the skin is bruised but no mark.
sorry I forgot to answer about pain when climbing stairs, yes I do, it hurts when I bend my knee.
