To be honest my health anxiety did not start until a few years ago and I was post menopause, before then a headache was just a headache, if I wasn't feeling well I always wanted to get to the bottom of it, by googling or getting books out of the library, just to sort it out and get better, even palpitation did not cause anxiety once I realised what they were, had the tests and the consultant reassure me there was nothing wrong with my heart.
The awful panic attacks and health fears and sheer terror came out of the blue after a operation seven years ago that went wrong, nothing to do with hormones or menopause, it was caused by post traumatic stress, and took a long time to get over, but still that sensible attitude to my health is not like it use to be.
We are all products of our genetics, life experiences and how are bodies cope with it all.
