I'm new here so hello all. I have a history of GERD and acid reflux disease. For the past few weeks I've been getting awful pain in my upper abdomen just below the sternum. The pain is also in my mid back on the sides of my spine. I went to the ER and they did blood work, CAT Scan and EKG. Everything came back normal. The pain in my back is horrific. I noticed that if I put my head down (chin to chest) with shoulders forward the pain starts as if im stretching my back muscles. It also starts if im standing for too long. Could this be muscle, spine, GERD or a combination of all? I cant stand it anymore. Its paralyzing and ruining my life. Im seeing my primary doctor, a chiropractor, and massage therapist tomorrow but wondering if there is certain questions I should ask each of them. I do take meds for the GERD twice a day plus Zantac 150 once a day. My gastroenterologist appointment isn't till the end of the month.
