In general, hard lumps caused by edema after mild inguinal hernia surgery may disappear in about one to two weeks; hard lumps caused by postoperative scar tissue will take six months to one year, and will also be affected by the patient’s physical condition and postoperative maintenance status. If the hard lump is caused by localized edema of the distal hernia sac, it will usually shrink significantly after two to three weeks and be gradually absorbed and eliminated. If it is the subcutaneous hard lump formed by some scar tissue formed during the healing process of the wound or the scar formed around the patch caused by the patch surgery method, it usually takes half a year to one year, and with the metabolic renewal of the tissues, the hard lump will slowly become softer and softer, and finally absorbed and disappeared. Patients can use local hot compresses or infrared physiotherapy to promote local blood circulation, which is conducive to the absorption of hard lumps. Inguinal hernia surgery after the discomfort, should promptly consult a doctor, under the guidance of a professional doctor standardized treatment, so as not to delay the condition.
