[quote BetsyBigNose]@radiateforme, I had similar symptoms, not to stress you out even more, but it could be a possibility. A few years ago I went to see my GP 12 times over the course of 9 weeks with breathlessness, not bring able to take a full, deep breath and sharp chest pains. She sent me away each time saying I was "overdoing it" (I wasn't) or was "slightly anaemic". It got to the stage that I had to sleep sitting upright as I couldn't breathe properly on my back and like you, I became incredibly anxious.
One day I had this overwhelming feeling of impending doom, it's hard to explain, but I just felt absolutely certain I was going to die. So I took myself off to A&E, where they found I had more than 15 pulmonary emboli (blood clots in my lungs).
Of course, your issue may be nothing like mine, (although if it is, it's easily fixed with some blood thinning meds) I just couldn't not respond when I saw you had the same symptoms and had been brushed off by your GP in the same manner as I was - it's just something to be aware of. I was only 32, fit and healthy and my oxygen saturation remained between 98-100% the whole time, the only way I was diagnosed was by a blood gas then CT scan.
I hope that whatever it is, you get sorted quickly, good luck.[/quote]
That's so scary. My uncle nearly died of a PE in his 40s. Glad you're ok now.
