Hello and welcome to the forum. Health anxiety is hard to deal with. It also makes it tricky to decide when something is cause for legitimate concern or not. In the case of chest pain that comes and goes, I strongly recommend going ahead and following up on this to make sure it is not cardiovascular in nature. Chest pain that comes and goes and intensifies at different times is one of the symptoms of a cardiovascular issue, however, there are also often other symptoms that accompany it. You need to rule this out though. Other symptoms would be shortness of breath, a crushing feeling, searing pain down both or one arm, in jaw, down back, etc.
There are gastrointestinal things that cause this also such as gerd.
Please see your doctor for evaluation.
Hi, I advise you to see cardiologist consultant & do a completed test which included ECG, blood test & treadmill test. I was fortunate that I went for the test after I experienced my unusual back shoulder pain, I failed the treadmill test, & there I went for angiogram, there I had 95% triple blockage. I had my bypass heart surgery on 19 July. Please go for cardiologist & don't hesitating.
