Sir my right side abdomen is paining since last week, in Ultrasound results everything is normal but still i am paining sometimes severe and tenderness all day and sometimes its paining under the navel, sometimes i feel burning sensation on urination, but no UTI infection, pH pus are normal, i have problems on passing stool like constipation, but no nausea or vomit no fever, the only thing paining n tenderness on my right abdomen, can it be an appendicitis,
