Hi The pain in abdomen is due to a number of causes such as an underlying infection or the presence of any abnormal mass or due to disease involving organs such as intestine or liver or other abdominal organs. Depending upon the cause, treatment is decided with medial as well as surgical intervention. If the pain is persistent from a week, please take a professional help. Please visit a General Surgeon or you can consult me directly via practo for further evaluation and management. In case of further doubts, please feel free to write back to me.
