high blood pressure
"Well I have blood pressure that is normally high, but sometimes normal.  I have only been on Hytrin for a few days.  The first day it made me very dizzy and fill very bad.  My blood pleasure went from an average of 160's/90's to 110's/60's.   I am only on 1 mg. I only have been taking a 1/2 a mg since the first day."
