Okay, I'm not a doctor yet, although I pretend to be (student, who definately doesn't know any where near everything). One bp reading, especially at what your's was, is not a major concern. A lot of people get nervous going to doctors and dentist offices (mine goes up by about 15, as does my HR). I would have it taken on multiple occasions, maybe at home if that's possible, and see if it stays elevated. If it does stay elevated, it is still in the mild HTN range, (> 140/90) which is normally treated with diet and exercise, and if it doesn't go down with that, then adding one medication usually. I would definately go and talk to your doctor, see if your bp is still high, and discuss other options than meds, which do have SE.
