yep, when the anxiety/depression acts up, my HA gets much worse and at 56 I know things can happen, it was bad enough when I was younger and had panic/anxiety but I was in good shape and youth was on my side. Yet I can totally relate to the post above about false positives, its not that its a false positive but I have had a lot of tests over the years and they always find something that is supposed to not be a problem, but still I would like to have a totally clean test. At least my first colonoscopy 4 years ago was perfectly fine. But an endoscopy found a polyp (taken care of) and a "soft submucosal" something or other that probably isn't anything but I will get it looked at again, and this time get it sonogramed, I know my heart is slow to relax (getting older, and heart stuff runs in the family), got a carotid artery scan twice, have mild plaque despite taking Lipitor for years, but I guess the emphasis is on "mild". Finally got a cat scan this summer that showed a bone lesion in one arm that was interpreted as an infarct, a liver cyst, and some small "hypodensities" in the kidneys that according to the doc was nothing to worry about. Oh yeah, when I first got sick decades ago and MRIs were new they sent me to get a brain scan and I had a pineal cyst, I was convinced that's why I had panic attacks--but turns out lots of people have them and recently one of my sisters had a similar scan and also had a pineal cyst. Also during that first time they told me I had mitral valve prolapse, but since then the docs say that I really don't have it, I think the definitions have changed for it over the years. Oh and I have BPH, didn't know that we men get to look forward to that with age, it sucks and I hope they come up with better options than they have now for it, went to one doc that scared me just showing me the equipment they would use to laser it out. No thanks, I'm counting on something better coming, maybe Nymox, soon. And because this latest episode is taking so long to resolve (there are better and worse days) I suspect things like pheochromocytoma or carcinoid, but its unlikely if I really analyze it. Like everyone says, fear of death is involved in this, but I really just want to be fine like before, b/c I know that worry doesn't change anything, and I'd just like to enjoy whatever years I have without feelings of anxiety or sadness unless I have a damn good reason.
