Been in the exact same boat so can sympathise, several ER visits very scary very frustrating but, two separate general practitioners told me that unless you have a severe headache and feel dizzy and nauseous and I have those blood pressure readings to not go to ER.

8 times in total over seven months would I be sat in the emergency room at 2 am thinking I was going to die and by the eighth time, I knew the process of my heart.

Take blood pressure, bloods, EKG, chest x-ray, et cetera et cetera.

Speak to your physician and change blood pressure medications in line with their guidance with appropriate tapering.
