Your blood pressure might just run high. You'll have to do extra work to stay on top of it because it won't be as easy to detect elevation, but if you keep with a healthy lifestyle (QUIT smoking!!), then you could be okay. Check it regularly for change. Unless there's something else going on, I would not take any medicine to control it. There's nothing WRONG with it. If your body is okay functioning with it as is--no other health problems as a result, or BP is not a result of other health problems--then you run the risk of throwing other things off when you change it.
The women in my family have low blood pressure. My normal is about 106/60, and it is RARELY higher than that. When I'm really cold, it's barely detectable. (I joke and say that I am hibernating.) It's always been this way. I have to demand that caregivers pay attention to it when it's elevated because they always want to brush me off with "Oh, that's normal," or "That's, actually, very good." I have to stop them in their tracks and say, "Normal for others. For ME, it's elevated, so please make a mental note and don't lump me in a group that will cause me to die because you were waiting for it to get higher." Before anesthesia, I always tell them, "This is what my NORMAL BP is, so if it goes higher, please know that that's elevated. By that same token, please know that if it's right here, this is the same as when I am awake and moving around."
I have known of cases where people took Valerian and noticed a favorable change in BP. Maybe that would be a good route for you...once a day or every other day. You know your body better than any doctor can.
I think that doctors are uncomfortable treating something that is out of their norm, so they want to shove you into your appropriate box so they can give you cookie-cutter prescriptions and diagnoses. When I was pregnant, my doctor--whom I loooove--was really bothered by the fact that I was not gaining much weight. He was afraid that I was actually trying to lose weight, because I had told him early on that I did not plan to gain 30 pounds just because that's what the books say. When he tried to make a big deal about the baby not gaining, I told him that we had just done an ultrasound, and the baby was growing fine. When I was heading out for maternity leave, some people were just realizing that I was pregnant. That was not by design, because I was eating literally all day every day. I was just eating good stuff, and I experienced some hormonal changes that I actually anticipated.
Anyway, I say all this to say that not falling into the "normal" categories does not mean that you are a health risk. Sometimes the only risk to your health is that you don't have the same baseline as most of what they've seen, so they've got to put in a little more work to keep up with YOUR particulars. This is why having a baseline is so important, to give them something to go by for YOU. "Normal" means "compared to the general population", and sometimes you're just gonna be different.
