Please can you tell me the difference between acid reflux and possibily bile.

I experience reflux regularly, but my Dr suggested that perhaps I may be suffereing from excess bile reflux. She suggested an acid test with a tube fed down the nose.

I experience pain in my chest (not heart) and feel that my throat is burning. I am often hoarse and I am concerned about what the effects of the continious reflux is having on my system.

I seem to continually be on Nexium and drink ant acids most days. My bed is raised up as well.

i have already had surgery about 8 years for a hiatus hernia and the reflux. What should I do now?

Thank you
