Hi ! Good afternoon. I am Dr Shareef answering your query. Your symptoms of abdominal pain and straining for passing stool points to a chronic inflammation/infection of your intestines. Most of the intestinal infections do come from food eaten from outside under unhygienic conditions. Therefore, you have to avoid taking food from outside if you do. Also avoid spicy, oily food, and include enough roughage and liquids in your diet. I would rather go for a stool test for ova and cyst and treat it if positive. The extra skin what you have felt could be an external skin tag, which occurs if anytime you had fissure in ano due to chronic constipation and straining. This could be known only by a physical examination and so I would advise you to take appointment with a general surgeon who could do that to diagnose the condition and then manage it appropriately. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
