GERD.
 I'm a 72 year old female, and have diverticulosis,gastritis, and esophagitis.  I tried to see three different doctors today, but all were booked.  I honestly don't know what to do.  It hurts in my chest, and I can hardly talk.

Summarized question: How to treat chest pain potentially associated with  diverticulosis, gastritis, and esophagitis?
