there are alot of answers but these are the fastest and best ways i know use the bathroom it won't always work but it usually does, and if it doesnt, see if you have a fever or need to vomit stretch...
If you want to get rid of a bad stomach ache fast then: 1. lay down 2. rub your tummy for a little while 3. use the bathroom cause most of my stomach aches are from when i need to use the bathroom
if the stomach ache is in the abdominal area then u could just be having period pains or just about to start one. it could also be food poisoning, eating too much or even eating too little.
