Swelling is often due to acute local injury and chronic strain, resulting in local bleeding, congestion, edema and inflammatory reaction, increased local tissue interstitial pressure, obstructed blood return, and stagnant blood stasis leading to the appearance of swelling symptoms. If you want to reduce swelling quickly, you should rest with local brakes and do not continue to move, because the more you move, the more serious the local swelling will be. At the same time, the affected limb should be elevated, higher than the heart, to promote venous return and facilitate the reduction of swelling. For swelling caused by acute injury, intermittent cold compresses should be applied within 48 hours to reduce bleeding and relieve local tension, which is conducive to the dissipation of swelling. At the same time, corresponding supportive symptomatic treatment should be carried out, including anti-inflammatory and analgesic treatment, blood circulation and stasis removal. Commonly used oral medications include fenbendazole and celecoxib, and topical medications include furosemide emulsion, traditional Chinese medicine golden cream, Yunnan Baiyao aerosol, etc. Local physical therapy, including baking electricity and spectrum irradiation, can also be performed after the acute phase, that is, 48 hours later, to promote the elimination of swelling. Some swelling is caused by other systemic diseases, such as heart failure and renal insufficiency, which lead to water and sodium retention in the body and swelling in the interstitial tissues. Patients should be treated for the primary disease, including correction of heart failure and renal insufficiency, etc.
