high blood pressure

I feel like my doctor is brushing off my high blood pressure. The past few weeks I've been in the 120/70 range but then today I was 134/88 and I had gained 4 pounds in one week also I have had a massive increase in swelling in my feet and some swelling in my hands. My doctor says it's completely normal but I wish he would act a little more concerned about it, what should I do?
