There are many causes of soft tissue edema. If the soft tissue edema is caused by simple trauma and the edema is relatively limited, it usually reaches its peak 3-5 days after the trauma, and then the edema will gradually subside, and it can be recovered in about 1-2 weeks. If the edema is caused by other reasons, patients need to identify the specific causes. For example, if the edema is caused by hypoproteinemia, the edema can only disappear after the hypoproteinemia is corrected. For edema caused by venous reflux disorder, edema can only disappear after improving venous circulation, etc. Therefore, edema can only be cured after treatment for various causes. For long time bedridden patients, patients with advanced malignant tumors have soft tissue edema, considering low protein edema, you can instruct the patient to increase dietary nutrition, if necessary, can also be intravenous supplementation of human albumin. It is recommended that the patient should pay attention to rest, and the affected limbs should not be overly active. Do not catch cold, cold will affect blood circulation, may be unfavorable to the subsidence of local swelling.
