The treatment for soft tissue edema should be treated differently, the main thing is to determine the cause, and the treatment methods are cold and hot compress treatment, strapping, etc., as follows: 1. Cold and hot compress treatment: The most common cause of soft tissue edema may be due to traumatic stimulation, such as after the arm is injured by external force, soft tissue edema will appear within a short period of time, which is manifested by the arm showing a swollen state. In this case, cold compress treatment is needed at the initial stage to reduce the occurrence of swelling, and hot compress treatment can be applied after more than 72 hours to promote the absorption of edema. 2. Binding: Other edema may be caused by blocked lymphatic vessels, such as after breast cancer surgery, due to the destruction of axillary lymphatic vessels by surgery, the lymphatic vessels are not very smooth, and the arm will also show a swollen state. In this case, the main treatment is to tie the lymphatic fluid in the limb to slowly return to the venous system, which can also be improved. The key to treatment is to determine the cause of the occurrence, and it is more desirable to know the cause and then treat it.
