I don't know that a chiro is the be all and end all for *all* injuries, having said that I always consult with mine, but I"ll go see my doc who has a sports background too. Are you sure you haven't seriously damaged (torn) anything?
For muscles, I am a big fan of ice. Not just ice in baggies, but an ice bath. I'm trying to think of how you would do a knee... I always go to see my friend who is a collegiate trainer, and she fills up a big tank with ice cubes, then cold water and then I get to immerse whatever body part I hurt in it for 20 minutes. It's brutally painful, much colder than ice packs, but it does wonders for swelling and inflammation; speeds the healing. Maybe use a cooler or a tub? I'm totally serious here.
At least ice several times a day, 20 minutes on, 20 off.
