Every hospital I’ve worked in runs a rapid access chest pain clinic, which GPs can refer to and will see you within a week with that story. They will have access to tests on the day (and more complex tests that they can fast-track you into) that will help with the diagnosis (whether it’s cardiac or not).
Phone your GP surgery now, and get an appointment in the next day or two. Tell them you don’t have chest pain now but have done in the last couple of days (if this is true) and they should give you an emergency appointment. Don’t just ignore it.
