It last for about 8 hours then it goes away.It hurts to even drink some thing & it's a very big lump.I heard something on the news about it being connected to gerd but it didn't hear what they said.It wasn't good though,i think you needed another scope & surgery.I've been on nexium for 6 years & if i miss it 1 day i have heart burn even from water.I don't eat spicy food,no spigetti,sometimes a lunchmeat sandwhich.I drink a cup of juice now & i get heart burn & then i have to take 2 tums.I know the nexium could be wearing down but it should be healed by now.I think something else is going on.
