@vra Hello, it seems like you have orthostatic hypotension. Orthostatic hypotension occurs when a person rises to a standing position from a lying or sitting position and is a result of falling blood pressure. Orthostatic hypotension is a form of low blood pressure caused by blood vessels failing to constrict when the body takes an upright position. The symptoms are a result of insufficient blood flow to the brain and typically include dizziness, light-headedness, temporary blindness, body dissociation, extremity tingling, or even fainting.
