FOR PAST 7 MONTHS HAVE HAD SHARP PAIN IN LEFT NIPPLE (I AM A MALE). MY PHYSICIAN ORDERED A MAMMOGRAM WITH NEGATIVE RESULTS-EXCEPT DIAGNOSIS OF MILD GYNECOMASTIA; HE THEN ORDERED A CHEST X-RAY, ALSO WITH A NEGATIVE RESULT. PAIN STILL EXISTS AND AT TIMES SEEMS TO RADIATE IN A LARGER AREA AROUND LEFT CHEST. AT TIMES HAVE HAD WHAT SEEMED TO BE A "HEART ATTACK", I.E. RADIATING LEFT CHEST PAIN WHILE LYING IN BED (LASTED ONLY A FEW SECONDS). MY PHYSICIAN HAS SAID PREVIOUS ECGs SHOW NO SIGNS OF A HEART PROBLEM.
ANY ADVICE OR SUGGESTIONS?
