Ragtop262 thanks for your reply. It can be difficult for people to understand it because they can't "see it".

The rotation is all I ask for so I'm not doing the same job for basically the whole day. I get the "well you're young so you can do it". If I try to say I'm in pain; I often get "are you really in pain".

People don't understand how PN is difficult at times but to them if they can't see it then it doesn't exist.
