Suggest Treatment For Avascular Necrosis

Hi, may I answer your health queries right now ? Please type your query here... Hello i got diagnosed in 2009 as having avascular necrosis. And due to have treatment to my femurs. My ex partner of 3years is showing similar pains in moving his right leg. All tho ive had blood tests 3times and negative for hiv and hepititus. I am still concerned about him. He is diabetic and may have pulled his leg or hurt himself during a diabetic hypo.i told him to have an xray .is it possable to pass this condition to another person even tho i've been given the all clear for hiv and hepititus? it dose worry me.
