Hi. I have been having chest pains in the past months and was recently diagnosed with GERD as my cardio tests all came back negative for a heart disease. I just want to ask if GERD could also cause left arm pain, dizziness and shortness of breath. I have been feeling those three every time i have chest pains. Oh btw the chest pains is like sort of tightness in the center of my chest. I just want to know if those are normal symptoms for those with GERD. thanks
