Last week I visited the Doc to check my BP, due to a slight headache, it read 92/190, I was given HCT 50, (Only Once) then I had my BP monitored, for 5 days, No drugs take, But the last read 80/120, three days ago, today I felt a bit abnormal, visited the Doc again today it was 170/105 (Was given HCT50TEN10) Kindly advice
