Sorry this might be longHi i'm sixteen years old and have always being in good healthLast month I went to peru and got a stomach virus which resulted in severe diarrhea, so i took cipro and it eventually cleared in three daysBut ever since this i've experienced nausea that was bad for two weeks and I still feel itAlso i feel this sensation of a lump in my throat nowadays.I had a stool sample and it turned out to be negativeI went to the doctor and he has given me zantac because he thinks it might be acid refluxThe zantac has not worked at all and it's been two weeksI'm starting to worry because I've never felt like this before and school started again so its hard for me to concentrate while I feel badMy mom thinks its all in my head but I still feel these symptomsShould I go see the doctor again? Any suggestions
