Patients with hard lumps around the navel are clinically common for the following reasons: i. The navel is accompanied by an umbilical hernia, which can often appear as an intestinal tube or omentum in the abdominal cavity protruding through the umbilical hernia defect on the body surface, and hard lumps can be palpated in the abdomen. Patients are often accompanied by swelling and pain in the abdomen. Patients are advised to improve local ultrasound and abdominal CT examination, which can clarify the size of their hernia defect. For umbilical hernia with small defects, high ligation of the hernia sac can be performed. For larger umbilical hernia defects, biological patch implantation is needed to repair the abdominal wall defect and avoid recurrent umbilical hernia attacks. Second, when the patient has soft tissue infection at the navel, a local hard lump can also be formed, which can be treated by applying Ruyi Jinhuang ointment and Bactrim ointment externally and taking amoxicillin and levofloxacin tablets orally to strengthen anti-infection treatment and promote faster absorption of local inflammation, which can reduce the symptoms of hard local texture and most patients can achieve better treatment results.
