I have a 12 year old child who is suffering from chronic osteomyelitis and has been struggling with it for over a year. She is in almost constant pain - worse at night, sometimes waking her up 3 or 4 times. She has been given 12.5 mg of Vioxx per day but it only lasts a shor while then the pain is back. I am leary about giving her Tylenol as well as Vioxx - it just seems like so much medication. I also struggle with giving her tylenol or advil every 4 hours every day(extra strength is the only thing that helps) as it seems so excessive. Any suggestions?
