Blood Pressure spiked to 175/93... should I go to ER?

It is like 3 in the morning I ate a burger around 11, and I woke up feeling very rushed. My blood pressure went up to 175/93 pulse 101, then about five minutes later it went down to 132/80 pulse 81. It has gone up again to 140/100 pulse 77... I think I should go to ER... I feel dizzy, just scared but maybe I am overreacting. I have panic attacks also.
