I have high blood pressure and take lisinopril, metroprolol and hydrochlorothiozide. Within the last few days, I have been experiencing short-term dizziness, sometimes when getting up in the morning and other times when lying down during a workout. Just now, I lifted a pan to look at the bottom and got a pretty severe momentary dizzying sensation. I should add that I have been experiencing allergic symptoms during this time, which is a common ailment I experience - but I take no medicines for it save for occasional Flonase. Symptoms included sneezing, runny nose and sinus headaches. I have also had dizzy episodes in the past, which always disappeared within a few days.
