How do I cure nasty gas and a tummy ache?

I don’t know what I ate tonight to cause this but, I’ve had some nasty smelling gas tonight! My tummy hurts and it burns and smells horrid when ever I fart. Actually my tummy burns right now.
What can I do to remedy this? Are there any home or holistic remidies ya know, besides medicines?

The best thing is to get the gas out so fart away.
