Whilst driving I suddenly had this strange sensation as if Id been shot in the head. My car felt like it was driving up a sudden hill, I loss my sight and hearing momentarily and when it came back I realized Id pulled over having indicated first but had no recollection of doing so. There was no pain and I wondered if Id had a small stroke. Im 56 and feel otherwise fine. Should I go and check it out with the doc, I dont want to go through a battery of tests and I realize I sound vague about the sensation. Can anyone help?
