Doctor, I'm having some weird symptoms: my legs are getting bent up and I'm knocking.

Symptoms can be a symptom of bloodless necrosis, which is a disease that destroys bone tissue due to a lack of blood supply.
Doctor, I feel stiff and muscular, so my knees hurt, my bones are pounding and my leg's getting sore.
I think you're going through some of the symptoms of OA, a sedimentary bone disease, and we can do some tests to check your diagnosis and discuss your treatment options.
