Can you speak with the oncologist clinic for some advice as to where else you can go ?
No good sitting and worrying when you can be proactive - even go to the emergency dept of the local hospital ?
If you reply to this post you can add your location so members reading this who are near to you can reach out and help you.
I know you are in Qld but it would not be right for me to advise your area, that is up to you. Is that up near Caboolture ? Qld members would have more idea than me š Sorry, I am way down south in Victoria.
