Shoulder Pads Snowboarding

What is the best treatment for sore muscles?
I went snowboarding on Sunday and took a good wipe-out. My body is incredibly sore, especially from the waist up (shoulders, ribs and back). I took some Flexeril+Vicodin, but that hasn’t helped much. I’m also using a heating pad on&off while at home. Is there some neat trick (or med) I don’t Know About that will help??
Suggestions??
A warm bath is a great suggestion, after that rub some Arnica gel on the sore muscles, rub it in until it’s soaked in and then either get a heating pad on low or just relax. It works really well to put the Arnica gel on just before bedtime.
