I've been a lurker for a little while but now wanted to post my own experiences related to health anxiety, partly in the hope that I'll get some reassurance, and partly to offer reassurance to others that it isn't just them with these kinds of worries. I suffer from health anxiety. This is the best board I've found for people who suffer from health anxiety, regardless of whether you have BFS, because many (if not most) of us on here also suffer from it. Whenever I've noticed a new "symptom", whatever it is, I've searched for it on here first, because I know someone else will have perceived the same symptom, thought they had some fatal disease, and received reassurance that they don't. It started for me in April last year (though I've worried about other symptoms in the past). I had a headache one day, which lasted over 24 hours, and turned into what felt variously like tingles, numbness or twinges of pain in my head for many months. Naturally, I thought I must have a brain tumour. Much googling of symptoms later, I read somewhere that such tumours can cause twitches. I have since come to accept that twitches caused by tumours would be nothing like those due to BFS (and would most likely be localised anyway). But at the time, I became ultra-aware of my body, wondering if I'd made this or that hand movement deliberately, or was it a twitch... and I started to twitch for real. I remember lying in bed a year ago, petrified as my fingers or toes twitched on their own, or some random muscle I never knew existed started twitching somewhere else in my body.The feelings in my head went away. But not before I'd had an MRI which confirmed there was nothing wrong with my brain (and still I was thinking, did they miss something?). While I was still worrying, I started to question whether I was feeling sick (another brain tumour symptom). Maybe due to anxiety, or maybe due to concentrating on this part of my body, or maybe due to some other reason, I developed twinges of abdominal (and chest) pain. This went away for a while but then came back, and has been back for about three months now. So now the (hopefully) irrational part of my mind is telling me I must have some form of cancer. It doesn't help that I also have heartburn related to this on occasion (it started around the same time). I'm hoping that I've just given myself IBS or something like that because of the anxiety. It doesn't seem to have affected my BMs though... I don't know...Having had BFS for about a year, I now completely accept that my own health anxiety and obsession over what my body was doing must have caused it. But there always seems to be some other symptom I'm worrying about. None of my aches and pains are ever severe, but I can't stop concentrating on them, worrying that they'll get worse, perceiving that they're worse than they are. In the last few weeks I've thought I could feel something in my throat - is it a tickle, is it soreness... and now I've started having twinges of pain in my ears. Could it be throat cancer? But then why would it have started with the abdominal pain? Does this mean it's another cancer that's spread? You see the sort of thought processes that go through my mind?! This must be familiar to other people on here. Hopefully someone will read this post and realise that I'm still alive, things haven't progressed, and so it must just be anxiety-related. It's much easier to accept that with other people than yourself though.Finally, has anyone else noticed that their twitches concentrate on the part of the body they are anxious about at the time? It seems to be my stomach muscles that are twitching a lot these days, presumably due to worrying about my abdominal pain.
