I have to go as my Mum is very poorly and needs me, I am so scared of something going wrong before I see her or have her see me in pain, it would really upset her. I do understand what you are saying and appreciate the fact that now my health should come first. I've always shrugged off any health issues I had in the past and never had time for me, put my family first etc. I am divorced and live on my own now and my family are all over the place so I don't have the support or backup I need when going to see my Dr who is really a great guy but doesn't know anything about PN. I will make an apmt to see him when I come back on 27th June and write things down so I remember. Thats a great idea about getting help at the airport I shall email the airline now and see what they can do, I feel like a fraud though do I really need a cart or wheelchair? others are so in need of them and people can't see whats wrong with me, its not visible per se is it? Have you flown and if so how did you feel on arrival?
