it's acid reflex and it stinks!!!!
sometimes mine will flare up just from drinking water....I did figure out though that tums help and so does drinking milk
Indigestion is a killer lol and it goes hand in hand with heartburn i get it all the time and Tums are my best friend! Also if it gets too bad tell your doctor and they can prescribe you Zoloft or Prilosec. It helps!
