I ve been having reoccurring sharp pains on the left side of my chest, directly under my left breast, seemingly in my heart. They are sharp stabbing pains that come and go, and last a few seconds to a few minutes. It s bearable, but very uncomfortable. I m only 50, so it s a bit concerning. I don t feel sick in any other way. Are these symptoms that I should be concerned about?
Hi,     I understand your concern.      The sharp pain on left side of your lower chest can be out of various causes ranging from simple muscle pull to heart problem.      Various heart conditions, lungs/respiratory problems/ digestive problems like GERD/ muscle, bone problems of rib cage can lead to such complaint.      It should not be neglected ,certain conditions need to be diagnosed/ treated in time  & specifically to avoid further complications.      You need not be tense, get yourself fully physically checked up by a physician, get investigated for doubtful conditons. Specific treatment according to diagnosis will help you.    Thanks.
