Hello, if you want to reduce the swelling as soon as possible, you can take anti-inflammatory drugs first, and then change the dressing. Early activity can also help to restore the swelling as soon as possible. Two days after surgery, an ultrasound machine can be used to perform physical therapy on the liposuction area to promote healing, speed up swelling, and reduce pain. However, it is recommended that you choose a regular and professional plastic surgery hospital or an experienced doctor, and choose anti-inflammatory drugs under the advice. Do not take the medicine at will. The medicine is poisonous and will harm the body.
