After the leg is swollen, the swelling can be reduced by general treatment or medication. 1. General treatment: within 72 hours of a leg bruise, ice packs can be used to prevent the swelling from worsening and reduce capillary seepage. After 72 hours, hot towels can be used to apply warm compresses to the affected area to accelerate blood circulation and promote swelling. 2. Medication: In order to reduce swelling as soon as possible, you can take anti-inflammatory drugs such as sodium heptaphyllum saponin tablets to promote inflammatory metabolism and relieve inflammatory edema. If the pain at the bump is obvious, you can consider using analgesic drugs such as ibuprofen. If the symptoms persist, you need to go to the regular hospital for examination and treatment as prescribed by the doctor.
