A couple years ago my husband went into the Dr;s office for a smashed something or the other (he is the reason we have insurance) and he's blood pressure was sky high. Like 160/90. It freaked the Dr out. They put him on med's right away. That is also when my husband started exercising seriously. See we had both quite smoking about a year or two before that. I worked out, he did nothing! It caught up to him in a very scary way. He was only 44 at the time and not over weight at all just not active. He went off the meds a couple years ago on h'es own. We monitored he's pressure with our own cuff and when it started to get back down to like 117/ 40 he said that's it. We still keep an eye on it. But he's was so high the Dr didn't even say " let's try diet and exercise first". Yours sound like white coat syndrome to me. I have that so much I monitored my pressure for a week for my Dr and wrote down at least 5 pressures a day. And you could see I was in the normal range. Good luck!
