I have had about 3 episodes of vertigo, very dizzy and spinning in my vision, has woke me up 2 nights in a row during sleep, I have had NO pain in ears, sinus s or jaw joints. when it woke me up I felt very hot all over my body, this lasted a few minutes and I went back to sleep, now I have bent over 2 times today and the dizziness hit me again moderately. my balance was affected but I did not fall, the went away in a couple of minutes. I have had a terrible sinus / allergy / or cold for a week now, lots of head drainage and congestion, affecting my breathing at night with my CPAP machine. any suggestions on what this might be?
