The best immediate treatment that I know to reduce the swelling is by applying ice on the swollen part. The moment you know you have hit something and you see some kind of swelling then immediately apply ice. Rub the ice on the swollen part, something like a massage. Remember most importantly to massage it for not more 10 to 15 minutes as this can lead to damaging the tissues within.
Once you are done with this, allow the part to warm for at least an hour then you can perform another ice massage. This is the best and also a very convenient way to reduce a swelling immediately.
