So. This is my 3rd time posting. Been having a bit of trouble lately. Yesterday went to my GP and told her I was having some double panes on the side of my left breast that goes into my rib side just right next to the breast . They did an EKG. they said everything was fine one line jumped but they weren't worried but they're sending me for an ultrasound. Well now I'm panicked. The pain is not constant. She assured me my heart is fine but I'm still panicked. Anyone ever had this pain?
