Your symtoms does not sound very alarming at the moment, so I would try the natural remedies, etc. and if you don't feel an improvement or get worrying symptoms, then you can request an Endoscopy to be done, in-office or out-patient basis.
With the Endoscopy your GI Doc can check for Hiatal Hernia, Barrets or Gastritis or narrowing, etc.
All the best, and let me know how you are doing.
