Cath! I've been sitting here for awhile, not knowing what to say to you! Are you alright? At first I had no clue what you were talking about and then I looked up Osteonecrosis. What a blow! I'm so sorry Cath! Hang in there! Cath, you sound like a lady that has a lot of support. Are you okay that way? Times like this you need someone near to you! I haven't cried for a couple days, this time its for you! What a horrible horrible disease. Antibiotics for pain? Do you have pain Cath? I am thinking you sweetie, huggggggggggs!
