Patients with subcutaneous pain in the belly are usually caused by the following two reasons: First, sebaceous cysts. Sebaceous cysts are superficial swellings that can form when the sebaceous gland opening is blocked. Sebaceous cysts are particularly prone to infection, which can cause pain and redness of the surrounding skin. Patients are advised to undergo anti-inflammatory treatment and, if necessary, surgery under local anesthesia. Second, lipoma. Lipoma is also a superficial swelling, which appears as a subcutaneous swelling, tough, lobulated, and relatively mobile, sometimes combined with pain, and the patient is advised to improve ultrasound examination, and can be surgically removed under local anesthesia. These two types of swellings are superficial and can be completely cured by surgery under local anesthesia.
