Here is an article that goes into detail regarding the best way to get rid of and prevent bruising. 

I recommend Arnicare gel and Rescue Remedy cream.  

Arnicare is a homeopathic gel that soothes the pain of bruising and encourages speedy healing.  

Rescue Remedy is a flower essence formula that can make the bruising disappear quickly.  It takes the shock out of the area and for me, it makes the bruise go away almost overnight!  

Otherwise, if you don’t have access to either of these, the standard remedy is an ice pack for 10 minutes.
