Very scary if you consult with Dr Google.
Which is why I always strongly recommend NOT to spend time doing that. "Dr Google" is very unreliable and most of the time only serves to frighten people, which in turn causes stress, and if you have fibromyalgia your symptoms will be exacerbated by stress.
I guess this will at first often be the case for anxious people who don't yet know how to use health information on the internet and put it into the right context.
Even then, I'd've thought such scariness would motivate more to get things excluded than it can paralyze. So easy for patients and docs to blame it on the fibro
before excluding "everything". That's what I read mostly on the forums as compared to only few people who are scared by and can't cope with possibilities. Being scared and getting stressed in this case I don't think is a bad thing at all. If it does get so, then that will be part of a bigger anxiety thing that needs to get sorted anyway and will lead to being scared whatever people do.
Our real doctors are usually so overwhelmed by our symptoms that any information helps what to ask them for, which types of docs or therapists may have a clue. Our fibro symptoms all seem to be "inexplicable", and new symptoms often also, and if docs blame everything on the fibro too quickly web-ideas that it might be something else, and even what, can help us self-advocate. So looking at web info at first sometimes feel scary, but it's part of getting net savvy and also fibro-savvy to get used to that. And if I compare it to things that really stress me, this is something which we
can get used to and knowledgeable about, rather than things like the news, which are always selected to be scary news.
In contrast youtube has become my best resource for pinpointing and treating my symptoms far better than any real life physio and especially doc. Altho of course I always went to these too (and some even helped a little bit), and I always get every new symptom checked by docs as well as doing a web search before, to know what to ask for. All my docs encourage me with this.
Getting used to web health ideas by putting them in context usually calms and gives ideas, allows progress esp. when like me docs are hopeless. It's part of self-education, knowledge is power and gives strength. My GP suspected cancer, the cancer doc didn't do anything, but looking on the web at what at least prostate cancer actually is and does calmed me. (That's been excluded now, other cancer forms haven't.)
Hehe, who needs the web when I've got a wife who keeps worrying and telling me I could have cancer and please try to get it checked further with someone more capable.
