Zovirax. Apply regularly. The thing I do is pop the fluid-y bit. It hurts, but once it's popped it can start to dry up, and then it becomes a scab, which doesn't hurt. Then it heals. In future, once you feel it go tingly, put the zovirax on straight away and the coldsore either won't form, or will be small and go away quickly.
