You need to understand that technologies are developing very quickly and we are striving for them. The Internet is almost everywhere, as well as access to it. And it's convenient ... We are trying to apply it everywhere to make life easier.
BUT it is not always 100% possible. Medicine is a practical science. A lawyer will tell you everything by phone.
And if you Call me and ask me what to do, my stomach hurts, then I will say that you may have an ulcer and it would not hurt to be tested for cancer markers. What ?! Without knowing your name, let alone a history, how can I tell you have flatulence? (which is more likely)
So that you call me in a month and say that I am a bastard, I deceived you, God forbid you had something serious, but I said relax.
Legally, neither I on the phone, nor the Internet has the right to treat you.
Another factor is that we go to the doctor on the third day of illness, and google in the first hour of illness. Of course, it will be worse.
Hopefully, knowing this will make it easier for you to relate to online advice. Which are not advice, but rather a blind guide to matching symptom to disease.
Be healthy! :)
Because a subjective description of the symptomatology is not enough for diagnosis, this is fortune-telling on coffee grounds and poking your finger into the sky.
For a more or less reliable diagnosis, in order to make any prescriptions, it is necessary to: a) collect anamnesis b) physical examination (this is actually inspect, touch, say a, breathe, do not breathe, look at the hammer, etc.). For many pathologies, any instrumental and laboratory methods will be required.
Without anamnesis and examination, all the doctor can recommend to you is some kind of homeopathy like ocylococcinum, in which there are definitely no active substances, but if you are convinced by the doctor will tell you what will help you - maybe will help you.
A little more has been written about the danger of searching for symptoms in Google more than a hundred years before the launch of Google. This is "Three Men in a Boat, Not Counting a Dog" by Jerome Klapka Jerome. The protagonist, using the reference book, found all the diseases, except for childbirth fever.
As for doctors from the Internet ... I myself often act as the very doctor from the Internet, for these purposes there is even a Vkontakte group ... I think I have every right to say that examination of a child with palpation, auscultation and percussion is an extremely important part of the diagnosis. And this is a huge fraction of what allows us to presume the result before analyzes and instrumental methods of examination. And what exactly examination gives an understanding of what examination methods we need.
