How can I get rid of this Viral Infection?

I have been sick for 1 week and 1 day. It started with freezing and high fever then went to sore throat and fever. and then the fever quit and the sore throat quit... Now all i have is swollen sore gums and jaw. I can't eat solid foods. and I have lost so much wait because of it. I look horrible. How can i get better faster? A big camping trip is coming up this weekend and I need to go. Anything that will help me be able to chew and swallow my food??? I have tried gargling salt water and peroxide and they both don't work. any help will save me?
