I'm confused about the differences between normal heartburn, acid reflux and GERD. Are they the same thing? Are they caused by the same things?
How do I tell whether what I have is ok to just treat with Tums or Pepcid, etc, or whether I need to ask a doctor about it? It seems to come and go but I haven't figured out if it's because of certain foods, or stresses, or anything like that.
Thanks for your help!
