Pain left side of stomach near ribs with nausea. Feels bruised like dull pain and shoots down left side. Have it for two days now?

Left sided pain. Any urinary symptoms or fever? Left sided flank pain may be a sign of a kidney stone (depends on your age) or possibly a kidney infection. Have you noticed any issues with your urine - darker or blood? If so - could be the infection or stone. Initially i would push fluids. If no improvement - probably best to see your doctor.
