Hello, I Am Experiencing Extreme Burning In My GI Tract--to

Hello,

I am experiencing extreme burning in my GI tract--to the extent my sinuses hurt, even my eyes. I also feel it in my intestines.

I am taking Omeprezole, alka-seller "gummies" and pepto-bismal. I started the latter two earlier today. The burning remains pretty extreme.

I do have Barrett's esophagus, but I never really had GERD symptoms. This is not your garden-variety indigestion. I am at a meditation retreat, but I could probably get in to see a doctor when I get home tomorrow.

Thanks in advance for any advice you can offer.
