I am a 27 year old female who up until now has been in relatively normal health. About a month ago I started having chest pains, after a visit to the ER where they took blood and did an EKG, they concluded that it was probably GERD causing the pains. I was given Prilosec which didn t help much, after seeing my Primary Care Provider, I was put on Nexium and Zantac which seemed to be helping for a little while. I had an upper GI test where I was given Barium to drink and had X rays taken. This came back and showed no signs of GERD at the time. Since then I have been back in the ER twice with chest and back pains, I have had another EKG which was normal, 2 chest x-rays which were normal, and also had my cardiac enzymes checked twice through blood work, and that came back normal as well. I sometimes feel a pain in my jaw and in my neck and shoulders. The pains seem to be very unpredictable and don t usually last for very long. Could this be GERD or does it seem like something with my heart?
