As someone with a very rare medical condition I find the internet a wealth of ideas and possibilities, but the system is to find out what other people have tried and then take any such evidence as you have to your doctor, and give them time to research the idea. If I left it to my GP's limited experience with rare conditions (not his fault, you just don't come across someone like me more than once in a lifetime of general practice) then I would never have tried anything at all. When I get a chance to discuss with other people I can find out that drug x actually
exists, or that treatment y is available to someone else in my NHS area when I have been told it's not.
We do have to be treated as sensible enough to process any information we receive via a reliable expert, however that reliable expert is not always your GP. There is more expertise in many rare conditions can be collected from patients than from doctors. Some patients are critical academics with the same sort of experience as GPs in reading academic texts and deciding what is and is not reliable evidence that something works. Once you have a diagnosis from someone experienced in anatomy, physiology, chemistry, etc. - the skills of the GP - then any other experienced academic is not doing a different thing from a GP if he goes away and studies articles in the Lancet and a meta-analysis of worldwide data. In fact, GPs are often those with the least time to do that sort of thing, especially for rare conditions. GPs are a wealth of expertise on new treatments for diabetes, angina, asthma, all the things in the "General Practitioner" magazine. They are not as likely to know of a cutting edge new treatment for Ehlers-Danlos Syndrome. In fact, for cutting edge treatments the consultant is usually taking almost as much of a leap in the dark as the patient. It appears from early studies that this treatment is safe and effective, shall we give it a whirl?
And what do statistics really mean anyway? If 97% of people found treatment x effective there is no higher likelihood in pure mathematical terms that I will fall in the 97% group than the 3% group. From many perspectives I really don't care what works for most people, only what works for
me. I have to beat off the desire for me to try the same treatment all over again because "it works for most people". I myself have tried it 26 times and each and every time it did not work and made me worse - what's to try a 27th time? Or the "have you ever tried..." No, I never tried the safest, most routine, cheapest first line treatment, my consultant and I decided to go straight to dangerous and radical surgery just for the heck of it!

I suppose there is a risk that the uninformed person does hear that a tertiary choice helped someone else so they try that first rather than a much safer simple cream or change of diet.
I think it is rather patronising to put people into little boxes of Doctor=God who knows everything about everything, Patient=Total Moron. I suppose I have a different perspective from many, it's not as simple as I have the occasional small problem, go to the doctor, he/she says oh yes we know what that is and this tablet will make it go away. My GP is more of a stepping stone to the national specialist hospitals that have enough experience to work with me, or a source of legal prescribing for the treatments I have researched and sent the research to his secretary. He trusts my judgement, and for the most part signs off whatever I want to try because he knows I have looked into it properly, not just Googled it and gone ooh, I've never tried yak urine, perhaps that will cure me.
I also need to be a partner in my own risk-taking, and I dislike doctors who say we can't do that because it's too risky - the risk is mine to take too, and your role is to explain the risks so I can choose whether or not I want to take them. Then if you personally do not want to put yourself on the line to be complicit in that risk I can look for someone who does, but it's back to the "good patient pat on the head" to just tell me that for you personally risk A is preferable to risk B, you are not in my pain. Apparently they say you should never perform an operation you would not want to have done yourself, but that's kinda nonsense because some people would just never, ever have a foot amputated unless it were going to kill them. Others get fed up with a neuropathic foot getting infected and dragging and cramping their lifestyle in a way that the person who hasn't had one will never truly understand, and just want it off. Why does a doctor assume to decide for a patient what suits his personal lifestyle?
And finally, since I am on my soapbox, I think some people need to be able to fully get their heads around incurable. Many times I have told someone I have an incurable genetic condition and been told they hope I find a doctor who can cure me soon, like the answer always
has to be out there. I think one of the reasons my GP trusts my judgement so much is he knows I fully understand I shall not find a cure and just want to ameliorate the symptoms. When one gets really desperate for a cure for an incurable illness that's when the most usuary charlatans come out, and when people start to go down the most extreme routes.
