I'm a 25 years old male, I've been smoking for 3 years.
Since last year, I noticed some palpitations, very mild chest discomfort on the left side…also some discomfort in my left arm specifically…so I went to two different cardiologists during this year, They both did an EKG and heart enzymes test and said that everything was perfectly normal and there is nothing to be afraid of.
so its been a year now and I do get the same feelings (chest and left arm discomfort, weird palpitations..) on and off, nothing painful at all but its just a weird feeling. so should I visit another doctor?
and the most important question is, is the EKG and the enzymes test enough to say that these symptoms aren't heart related?
