Hi there! Yep, you have classic reflux symptoms. I had all those and then some like bad taste at the back of my throat all day long, hoarse voice by the end of the day, nausea, tenderness at the point the stomach/esophagus join, actual regurgitation of stomach acid when bending over to name a few.
Get to your doctor and ask for an endoscopy to be done. Even though you have the typical symptoms, your doc should take a look at the esophagus to determine the extent of damage before just prescribing PPIs. Dietary changes may also be in order, and elevating the head of your bed 6" with blocks may also help.
Good luck and keep us posted,
Katie G
