At my age do i have to see a doctor if i'm having chest discomfort?

Yes, doctor can exam: A person with chest pain symptoms usually has to go to his doctor (or even to the Emergency Room) to be checked right away for a heart problems, UNLESS there is another convincing reason for chest pain (decided upon by talking with one's doctor). That means not waiting at home to see if it turns into a more serious condition. As the saying goes, "better safe than sorry."
