GERD? Does anyone else have it?

I was just diagnosed with GERD at the ER today and was curious what other peoples' symptoms are. I went in today with pain in my chest, shortness of breath, and a numb left arm. I was given a bunch of tests including a CT scan just in case I had a blood clot and nothing was found. I was given an OTC antacid to take but I can't begin it until tomorrow when my pharmacy is opening. As for now, my left arm still hurts and have some pain breathing.
