Painful pressure on the left and right sides of the navel is associated with acute enteritis, ulcerative colitis, intestinal tuberculosis and other diseases. Most acute enteritis is caused by overeating, poor diet, and other factors. During an attack, there is inflammation in the intestinal mucosa, so it causes pain due to irritation of the lymph nodes in the intestinal wall. The intestinal tract is mainly around the navel, so during an attack of acute enteritis there will be pain on the left and right side of the navel on pressure. In an attack of ulcerative colitis, there is an ulcerated surface on the mucosa of the colon with impaired function, and there is also pain on pressure when pressure is applied to the colon area. Since the colon is located around the abdomen, pain is experienced when pressure is applied to the right and left side of the navel, and mucus-purulent stools are also present. The main symptoms of intestinal tuberculosis are abdominal pain and fever, and the pain is mainly around the navel, so there is dull pain when pressure is applied to both sides of the navel, and even a mass is felt in the right lower abdomen.
