Suggest Remedies For Bruise On The Right Hip And Buttocks

So 9 days ago I slipped on the ice and landed on my right hip/buttock on the edge of a cement stair. There was baseball size bruising by morning, along with swellings and pain. Since then, the bruise tripled in size. Dark purple and red, some spots are now yellow but those areas change back to purple too. Now I have a hard lump and have always had obvious swelling because of the lines my not tight underwear leave. Worst part the past 2 days is this deep zinging burning sensation. Almost a ripping feeling too. I m thinking deep muscle bruise with pressure on the nerves. What can I do besides NSAIDS and icing?
