It is highly unlikely that these black lines are related to your medication, especially since you have been taking it safely for six years. These lines are more commonly caused by minor, unnoticed trauma, friction, or other benign skin conditions.

Blood pressure readings like 98/98 or 104/98 mmHg are unusual because the diastolic (bottom) number is normally lower than the systolic (top) number. A diastolic value around 98 is considered high. This could be due to a measurement error or an underlying health issue, so it shouldn’t be ignored. The safest step is to recheck your blood pressure with a properly calibrated device and consult a doctor, who can determine the cause and guide you on the right treatment.

A blood pressure reading of 90 to 100 is generally considered low or at the lower end of the normal range, rather than high. Medication is not usually recommended unless your doctor identifies an underlying cause or you are experiencing significant symptoms such as dizziness or fatigue. It is important to monitor your blood pressure regularly and consult your doctor if you have any concerns.
