How long does it usually take for the swelling to go down?

Due to the different degrees of abrasions and swelling, the time to reduce swelling after abrasions also varies, without hematoma and infection, generally ranging from 3 days to 10 days.
If the patient is a minor abrasion or soft tissue swelling, it is generally recommended that a cold compress be applied within 24 hours of the abrasion in order to reduce the exudation of the local capillaries, and a hot compress be applied after 24 hours of the abrasion to promote local blood circulation, and the swelling will gradually disappear in about 3 to 10 days.
However, if the patient is a more serious abrasion or hematoma, infection and other conditions, the patient affected area will be relatively longer time to reduce swelling, the longest time about 1 month, because at this time the patient may need to be puncture therapy and anti-inflammatory treatment.
It is recommended to consult a doctor for timely examination of abrasions, and carry out appropriate treatment under the guidance of the doctor.
