How can I cure muscle soreness and aches?

I walked around my college campus for 4 hours yesterday before going to a concert where I danced and moshed and crowd surfed. Afterwards I went dancing for another couple of hours. Today I have tons of bruises and am really sore. I don’t know how to remedy this in a dorm because at home I would just take a bath but we don’t have a bathtub. What can help?
