My husband had a brain tumour which was in a cavity at the base of his skull, the surgeon was able to remove the tumour on 24th July, unfortunately he fell from his bed and had to go to theatre again 2 days later. He is taking steroids for the last 8 weeks and has become very weak, he is to have an MRI scan next week and has been told he needs radio therapy 1 or 2. I am just worried as he has deteriorated over the last week, feeling sick, shaky on his legs .My question is, is this a normal reaction after surgery?
