I Am Only 21, Almost 22 Years Old, Male, And

I am only 21, almost 22 years old, male, and I went to the doctor this Saturday due to high blood pressure issues. The doctor changed my blood pressure script to eDarbyclor. While I do feel a bit better, I am still having a fluttering pressure in my chest that comes and goes but coming more than going and it's an uncomfortable feeling. Should I go to the ER? or is this common?
