I just thought I should let you all know: After DH's catheter examination, the docs gave an all clear on the heart front. Nothing wrong with his heart, and, since the did a cat scan of his brain, too, to be on the safe side, his brain is OK, too. They suspect something neurological (whatever that means) and sent him back to his GP for further proceedings. Well, it doesn't take away the headaches, pain in his arm, dizziness, and nausea when it occurs, but at least it removes the fear from our hearts. Our Christmas will be a good deal brighter. Thank you for your support!
