Most likely your blood pressure is high because of your infection. If the higher number is 160 you are just on the border between borderline bad and pretty bad blood pressure. Blood pressure measures how much pressure is going through your veins. The higher the pressure, the harder that your heart has to work. In older guys high blood pressure can result in heart problems including heart attacks, as well as a loss of libido too. But you are young, so I am not as concerned about your high BP reading. Just keep taking your antibiotics on the doctor's schedule and both the infection and your blood pressure should reduce by next week. See, it wasn't so bad going to the doctor, now was it???
