You need to go to your Doctor and perhaps have him/her refer to to a specialist.

SSRI medications can cause the Lower Esophegeal Sphincter to relax, allowing for stomach acid to back-flow into the esophagus. However, this is often a an early side effect that resolves over time. My personal experience with SSRI medications has been that I get daily heartburn whether I take them or not.
