Hi! I am a 56 year old female. I am new to this board, unfortunately not to knee pain. About 25 years ago, I was dx with patella femoral syndrome. I have been pretty much bone on bone in both knees- with the right worse than the left for 5-6 years. Recently, I have been experiencing an achy/throbbing feeling behind the knee caps with a kind of spasmy feeling extending down into my calfs. Is this a common symptom as the knees start to go? I am sitting with a heating pad on my knees!!!!!
