High blood pressure, leaking aortic heart valve.

ok so im 27 and have a leaking aortic heart valve along with high bp. I've been having chest pains, shortness of breath, headaches,hot flashes, dizzy spells. I developed high bp 3months into my pregnacy, had a high risk pregnancy from then on had a c-sec 2weeks early because of the fluid and bp. Its now a year after my son was born i still have high bp. my cardiologist has me on 800mg of labatalol,100mg of hydralazine, klor-con, and hyrochlorazine. a few weeks ago i had a horriable spell at the store where i got hot, then dizzy and blacked out. There is no evidence of me falling during this time, but when i came too i was confuse didnt know where i was or whos cart i was pushing. Went strait to cardiologist and she did a CT of my brain. Everything was normal, now having lots of blood work and urin testing done, waiting on results. But does anyone have a idea or anything about what maybe goin on? Sometimes at night while i sleep i get woke up from what feels like my heart pound then like waves of warm tingling all over my body, then almost like im drunk when i close my eyes,its like im looking through a kalidascope. dizzy feeling.
