Pain in left back breastbone. Problems?

I'm currently under medication for anxiety for last one month..for last couple of months, I'm have weird pain like sensation in my left breastbone and sometimes it's radiating to upper chest and rips and hands with some chest discomfort. If I apply pain relief gel in back breastbone and chest, I feel better...Since I'm a health anxitey patient, I keep taking tests for last four year..my last TMT taken 3 years ago and it was good and my last echo done on 9months ago and my heart is fine..but due to this, I'm keep suspecting about my heart condition..I have to say I was suffered with esophagus ulcer couple of years back and taken some medications at that time... Is that back again, so my condition and symptoms is still related to anxiety and GERD? Or am I having some heart problems?
