I never had heartburn/acid reflux till I got pregnant and it totally sucks. I live by Tums and the 150 mg Zantac.
This. But when it got unbearable my doctor gave me a prescription.
X100000... although the pain is never in my back, its all up front between my breastbone and I gurgle/burp (not real burps) all the time! At night, I try to not eat to close to bed time or acid will come up in my throat when I try to sleep.
I would ask the dr at your next apt about the pain, the only time I had pain like that which radiated to my back was during a gallbladder attack that i had after surgery a couple of years back.
