It was just assumed I had too much acid.  The  first time I had pain and it 
went through to my back.  The doctor  assumed I had an ulcer and didn't think 
testing was necessary since it  was my first problem.  The Zantac worked great 
(took it for 6  weeks) and I never had a problem again with that.  Then the 
other  time I was having lots of chest pain which we figured out was really  
coming from the stomach or esophagus.  She assumed it was from  acid splashing 
into the esophagus (acid reflux) and prescribed Prilosec  which increased my 
pain.  So I took Zantac again and it made  everything feel good.  I take it now 
if I overeat or whatever and  have a one time burning pain in the chest. Often 
Tums or other antacids  made me feel like I'd eaten a concrete block.
