Different triggers that cause redness and swelling of the incision are treated differently. If it is caused by infection, topical medications such as iodophor or Pepto-Bismol will need to be used for dressing changes, as well as oral or transfusion antibiotic treatments. If the infection, redness and swelling are serious, it is even necessary to cut the incision again to remove the infected tissues within it, and then perform regular dressing changes. If you consider the redness and swelling caused by localized scar proliferation, you can put on scar paste or apply scar cream, and at a later stage, you can also take drugs to inhibit scar proliferation, such as Triamcinolone acetonide, and if necessary, you can also go to the medical aesthetics department of a regular hospital for treatment. If the suture rejection is considered, usually no special treatment is needed, but severe symptoms need to incise the incision again to remove the suture in order to get better. In conclusion, if the incision continues to be red and swollen, it is necessary to seek timely communication and treatment from the attending physician.
