high blood pressure
"I am 21 years old and I have high blood pressure. I was on hydrochlorothiazide for approximately 2 weeks when one night about 3 hours after I took it, I had an allergic reaction. My hands, face, lips and feet swelled up.  I was itching and had difficulty breathing. My mom rushed me to the ER. If you have ANY of the previous symptoms please go to the ER as soon as possible."
