Thank you everybody once more – this doesn’t seem such an uncommon problem and it’s funny how things you once didn’t bat an eyelid about can suddenly become a major issue. Yes, I was told about a risk assessment having to be carried about before rails could be used – apparently 5 residents in dad’s CH of 40 have them. Sorry craftyviola to hear about your MIL, that's v sad and hope the head scan isn’t as bad as you fear. After a long sleep have woken feeling better so will try and enjoy my day off from visiting and hopefully by tomorrow the arnica might have had a little effect!
