There are many causes of swelling, and the measures to intervene are different for swelling caused by different reasons. The main measures are as follows: 1. If the subcutaneous hematoma is caused by trauma, local cold compresses can be given within 24 hours after the injury to relieve pain and reduce edema, and hot compresses can be given after 24 hours to promote local blood circulation, which can help reduce the swelling; 2. If the morning eyelid edema is caused by lack of sleep or drinking more water before sleeping, the edema can subside after rest or local cold compresses; 3, If the edema is caused by long-term oral hormone drugs, the edema can be reduced by adjusting the treatment plan or by adding diuretics; 5. However, the improvement is not obvious in patients with advanced tumors, and the healing process is very poor in most patients.
