Lately, I have been experiencing throbbing pain, kind of a pinched feeling, off and on in my left breast region. This is usually accompanied kind of a nauseous feeling. I went to my family doctor, and he tested my blood pressure and monitored my heart rate. He found everything normal, and suggested I could be suffering from acid reflux or something similar. I still have the same feelings today, and it doesn t seem to be getting better,At times I also feel tired or light headed, Any thoughts ? I am tempted to go the ER but what would that accomplish?
