Hello I had Diarrhea for 3 days and a Tummy Ache for 3 days But it went away yesterday & my urine has no smell but it's dark yellow! I'm concerned! ?

Dehydration. Hi, from your description it seems you have lost a lot of fluid from the diarrheal losses and your urine is more concentrated because of it. In the next couple of days drink a lot more fluid and your urine should become lighter.
