Try a really hot compress (as hot as you can stand it!!) - i just got rid of a massive blindy and it took 3 days to come to a head and was sooooo painful - but once it came to a head and i drained it its pretty much disappeared - try not to squeeze it as it will spread the infection!!!
Regarding a concealer try a "green" concealer. Many brands make one, it's probably best to go to one of the cosmetic counters at Myer or David Jones. The green colour covers the red perfectly and once your foundation and powder is applied you won't see any colour at all.
Good luck - here's hoping your wedding is everything you dreamed it would be. xx
