Hi everyone (I namechanged and haven't been on these threads for a while, but was a ways back)
On Googling --
As far as health anxiety is concerned, Google is pure evil. (Ironic, really, considering their company motto used to be 'don't be evil'.)
It's worth remembering that there are technological and business reasons as to why Google (and other search engines) shows us the results it does, that have nothing to do with our actual health.
When you search for stuff on Google, two things happen.
First, the primary business aim of Google is to get you to click on things. So it's designed to show you things that you will either agree with entirely, disagree with utterly, or scare you completely. (Facebook does this too.) Our health anxiety fears fall into the final one, for the most part.
It is basically a psychological trick, and why search results for frightening (and in most cases extremely rare) illnesses come up so high -- because people click on them.
The other thing that Google does: over time, it stores information about the searches that you do and uses this data to fulfil future searches. If it learns that you often click on search results about alarming/serious illnesses, for example, it will show you more of those. So its results are increasingly based on what it knows you've searched for and clicked on in the past.
DH and I did an interesting experiment a few weeks ago. We both went out to a 4G area and did a search on the same term. I used Google Chrome on my phone (which has all my web browsing history on it) and he used Safari with the cookies and history cleared.
We got totally different search results. I got links to ultra-rare Fatal Ibbly-Wibbly Disease*, he got anxiety and food intolerances. It was really shocking. (Surprise surprise, my issue turned out to be anxiety and a very mild food sensitivity. And not Fatal Ibbly-Wibbly Disease.)
Dr Google is the diagnostic equivalent of Chicken Licken, who thinks the sky is falling just because an acorn fell on his head.
Just thought I'd mention this, in case it helps anyone. It's a very personal thing but when my HA is bad I get some rational comfort from remembering how bloody awful a doctor Dr Google actually is.
