Why does my stomach hurt all the time like im going to throw up and what is the best way to treat it?

GI problems: There are many possible reasons for nausea. Please see this extensive list of possible causes of nausea by Mayo Clinic: http://www.mayoclinic.com/health/nausea/MY00572/DSECTION=causes * Probably the simplest way to reduce nausea is with Ginger. You can drink slightly flattened ginger ale or nibble on crystallized ginger. Or pour boiling water over ginger & steep x 5 min in a pot & sip.
