so it has been two months and i have pain radiating from my knee. my ASO was high and my orthopedic said it was arthritis. but another doctor said that it was nothing and my ASO was high because i had strep throat. he didnt pay attention much to my knee pain. My ESR was high (82) and that is the main thing that has me worried. i also have uric acid. but after 2 months the pain still comes and goes. my x rays and CBC were normal. since x ray was normal, does it mean i dont have bone cancer? please help
