Now I'm scared

I am not sure if I have mentioned it but I have hurt my back.
To try and help I have been treated to a hot water bottle.  I have not had one of these since I was a child, many many many years ago. In those days my mum filled up the bottle, gave it to me and said Goodnight. She never once warned me of the potential dangers lurking in and around that bottle.
The blip is a list of potentially deadly consequence's of using the hot water bottle, as listed on the wrapping. Had I realised the risks I would be taking I would not have bought one.
Well I have now filled the bottle with hot water and have it resting on my back. If you see no more blips from me you will know it got me. But I can not complain that I was not warned............
