OK went to my gran's this morning; on walking up I felt fine; as soon as I sat in her house I was dizzy. Walked up the road about half an hour ago; on sitting down at my house was very dizzy; weak; sore neck and chest; numb patches in face; heart pounding, felt like I couldn't breathe and convinced myself it's bad. have dragged myself upstairs and sitting down but still feel funny. Mum says if it were bad I'd be sweating and pale and unable to talk but I'm really scared. Surely 4 ecgs cant be wrong?
