Had costo.area below left rib have a dull ache when press hard.sometimes it come n go.it is just below tender area in my rib.can it be from the costo?

Below rib pain/costo: Could be costochondritis or could be gastritis with or without H pylori or could be from colon -constipation.if coughing could be musculoskeletal from cough . For costochondritis use motrin /advil /aleve if not allergic; for gastritis need ranitidine/ prevecid, for constipation use milk of magnesia (magnesium hydroxide) 1 tablespoon 2 x a day x 4. Would follow up with doc
