I have had several dizzy spells lately. Sometimes I just move my head, sometimes I am in the heat outside, sometimes exertion, sometimes sitting still. Today I was outside spraying weeds (natural mixture) and I was so dizzy I could not walk without holding on. I barely made it to the steps to sit down. It passed after a minute or so of sitting. I put my head down for a bit as well. My ears seem to close up and my face does not feel normal but I can talk fine, I am cognizant of surroundings and my face is not contorted at all.
