In brief: Antiviral meds
Most cold sores are a type of herpes (not the same type usually that causes genital lesions) and if caught early (ie when the area starts to tingle or burn) can be suppressed with an antiviral medication like Famvir (famciclovir) or acyclovir.
If you can't get a script for one of these meds, try applying ice to the area 4-5 times a day as this will inhibit viral replication and speed healing.

In brief: Cold sores
There is no really effective treatment for cold sores.
There are hundreds of treatments that work for some people. For cold sores on the face or external parts of the lips, an oral antiviral medication like Acyclovir will help if started early. For internal oral cold sores, you can have a physician try either silver nitrate application or topical cortisone.
