I don’t know where you live but if you live in the UK the only way to receive “free” NHS-healthcare is to be obedient to every wish/demand of a NHS-GP/specialist, whatever their wish. If you prefer to keep your dignity and refuse, you are from then on – as a result - only seen by medical students or young doctors without experience. There is no positive medical outcome and it is a waste of your valuable time. When I tried to get medical help at Accident/Emergency I was treated very badly after giving my NHS-number. (They obviously checked me up on the computer). No point in trying that either. You won’t find a female agreeing I am telling the truth because many cannot talk about it in case their family or husband finds out. If you study my former posts on IHD you will notice that I was mainlh attacked by females and it speaks for itself.Don’t offer yourself for medical trials too easily. In my desperation I went ahead and was lucky to survive. I was given “Retuximab” and “Corticosteroids” for my ESRF and only realized later it was an experiment. It was known I had not seen a NHS-GP for years. (last time I saw a NHS-GP was on 17th February 2004) and so I was “anyone’s game”, as I was told once by a charming doctor. Retuximab can be very dangerous, some patients lost their wits after taking it. I heard similar stories about other experiments, i.e. stem-cell-trials etc.
