Yes, High BP can cause arterial and heart damage over a period of time. It is best when treated early. You can also monitor it by buying a BP kit - some electronic kits are okay and some are not exactly calibrated but may give you some type of inidcation. You should keep a log of day and time. Also, put down what you did that day for workouts, cardio, drugs, alcohol, etc. to see if their is any correlations. Good luck,
