Blood pressure and dizyness. Shifts.

Hello, I'm 26 years old working as an software engg. Recently from past few months or so dizzyness is getting increased in me and I use to get headaches and head reelings. Recently when I went to health center they checked my blood pressure it was 153/93, it was little high. Later next day again I was not well and I had fever so went to check my BP it was 183/148 which they told it is very high. After medication it is now in 150 and 140 in next days..please suggest me how to start with the treatment. I have synus problem too. Basically my work timings vary every week. Every alternate week I'm working in night shifts and the other alternate week in morning shifts. Thanks in advance and hoping for better suggestion for my current situation
