High blood pressure with nothing apparently wrong

Blood pressure of 210/134…went to urgent care and they referred me to ER…they did EKG, blood test, urine test and x-Ray …they found everything came out normal…yet I am running high blood pressure, heart palpitations, chest pain, headaches and dizziness…
What else could be wrong that they didn’t find? They told me to go to my doctor for a follow up but why? if they didn’t find anything, what is she going to find?

It could be because of anxiety also, consult your doctor immediately as blood pressure is too high. It can damage organs.

first bring blood pressure down and then your doctor can find out reason.
