I have a pain in my chest that is worse
You should be investigated
As per your description,it looks like Gastroesophageal Reflux disease (GERD).But,Upper GI endoscopy has to be done to exclude other problems like Hiatus Hernia,Growth in the Esophagus or Stomach etc.
If Endoscopy is normal,you can use Rabeprazole20mg/Esmoprazole40mg with Domperidone for Heart burn.
Please consult your doctor and proceed further.
Nothing to worry.
Hope I answered your query.If you have any questions,I will clarify further.
Wish you good health
