Hi. Im a GERD sufferer for more than a year now. I have observed that everytime i get upset, excited, surprised, my heart is racing. i have palpitations and i feel the pressure in my chest and worst, accompanied by hyperventilation. My cardio said eveything is fine nothing to worry. he said that my hypersensitivity system is very active. He never prescribed me any meds for this since he said everything is fine. it could also be ssociated with anxiety. please help me how to deal with this. thanks.
