I have had a stomach ache for about a week now. Sharp pain in the upper area. When I poop my stool looks like saw dust, there is no blood though help?

See your doctor. Significant stomach pain that doesn't go away for a week should be evaluated by your doctor- there are lots of possible causes. Sometimes a trial of acid blockers (eg, ranitidine, or omeprazole) helps eliminate gastritis or ulcers as the cause.
