For the past month I have had a tingling pulse sensation near my left nipple region which does not stop. Without even trying to feel it , it happens. I have done all tests such as echo, stress test and ecg and all say that it's normal. I also am on Gerd medication which has reduced my acidity and even some pain in my rib area. But this pulse sensation near my left nipple hasn't gone and even spreads to my left arm making it numb.
I'm really scared please help me a bit here
