I have GERD. Not fun let me tell you. It has gotten better over the last couple years. But when I get a flare up, it sucks. I get pain down my arms, up into my neck, my chest hurts like hell, and even my hands and fingers hurt. I was on prescription meds for it, but my body got immune to it so it didn't work as well. So I stopped taking it. Now when I get a flare up, I just chew some Tums. It helps a little, but it still sucks. Definately go to the doctor and get checked out asap. You never know what it could be. Just thought this info might help you out.
