This situation is normal because of the following reasons: 1. In the process of appendicitis surgery, the skin, subcutaneous, subcutaneous tissue and muscle, peritoneum, into the abdomen need to be cut layer by layer, in the process of closing the abdomen need to close each layer, so after the surgery will feel the surgical area is hard relative to the surrounding tissue, it takes about three months to subside. 2. After the surgery, due to the edema of the tissues around the area will cause the area to be hard to the touch, but it is normal, as long as the patient does not have obvious redness, swelling, pain, or oozing, there is no need to be nervous. In addition to hot compresses, local physiotherapy with a warm water bag can promote the inflammation to subside. Pay attention to a light diet, do not eat spicy and stimulating food, and increase activities appropriately to avoid intestinal adhesions, intestinal obstruction, etc.
