Basically I've never had heartburn/indigestion so I have no idea what it feels like. For the last 2 days I've left like my food hasn't gone down properly and it's up in my throat the whole time. I'm not really in any pain,it just feels uncomfortable. I HATE taking medicine, I'm such a baby and it makes me gag but hubby literally just force fed me 2 spoonfuls of gaviscon and it hasn't really done much...not sure how long it's supposed to take to work? Does this sound like indigestion?
