I was diagnosed with arterial venous malformation after an "episode" while teaching that rendered me unable to speak anything but intermittent garble. There was no pain involved, but it lasted about an hour and a half and was very scarey, because I couldn't tell anyone what was going on. The neurologist ordered a cranio angiogram and, although there was no pain involved there either, I came away feeling a little addled. Since then, I've been feeling quite unsure of my speech (eg. I'll start a sentence and then won't remember where I was going with it ... not good for a teacher!) But my main complaint is that I've had a constant brain fog and also a niggling headache since the angiogram. It's been two weeks now, so should I go back to my doc? I've got an appointment with my GP in a week ... should I wait that long, or could something be really wrong here, as a result of the cranio angiogram?
