I had severe pain from right side of my stomach till the rectum then it was considered as infection and antibiotics were used and initially a strong painkillers injection. A week later I was not feeling hungry and unable to take sufficient food. Endoscopy done and detected duodenalulcer. Now my lower abdomen is swelling I feel . I had been suffering from irritation in intestines since long back. Pls suggest what else diagnosis is needed. I am using pantocid 40 m now.
