Simon has, for the last fortnight, pain in his jaw joint. If he hadn't had rx, you would say he's done some ligament damage from the way he describes it. It is tender when he eats, but when he applies pressure to the joint the pain lessens. Does this sound like radioosteonecrosis?

He has an appointment with his ENT on Friday, but no-one has mentioned HBO, whereas when I research HBO it is suggested it is used to PREVENT or treat "necrotic" tissue as a result of HN cancer radiation therapy. If that's the case why don't patients have the option before or during rx, or is necrosis not so common? Fremantle Hospital has extensive HBO facilities, so I know he'll be able to have the treatment if needed, but am surprised it wasn't spoken about during the course of treatment as a possible side effect.
