Thanks for your advice everyone. I know this treatment works and I'm pretty sure Steve is aware, or starting to be aware, of how well it works and that the alternate is not worth contemplating. It's not HBO as such that gives him severe anxiety attacks. It's sydney. He's a country boy and doesn't cope well with crowds. He's shy also and likes his space. I know this sounds silly when you consider what he's been through but of all his strengths, big cities aren't one of them. It's really debilitating for him. But I do have a plan. Where we used to live has a HBO chamber as it's the major hospital near the Great Barrier Reef. Townsville is no where near as big or as busy as Sydney. We were thinking of going home so this just gives us even more reason to follow this idea. The treatment will be no more than a 10 min drive from where ever we live so it will work out well for Steve. Alot, lot less stressful. Still waiting to hear from the hospital as to dates for his pet and biopsy but this is something I will be putting forward to them with regards to hbo when the time comes. Fingers crossed all of this works out for us. If not I'll drag him to sydney, anxiety tabs to the hilt if I have to. One way or another I will get him there.
