I have pain on the right side of the lower abdomen that moves to the lumbar area, the pain comes suddenly. Bowel movements are irregular and slow, the symptoms began three days ago. I have many cramps.
Abdominal pain that moves to the back can be: appendicitis (pain in right quadrant), gastroenteritis ( intestinal flu or food poisoning) up to even more serious problems such as pancreatitis. If your symptoms are still go to the doctor.
