Sounds like you are looking for any excuse to avoid going to get medical help.
If you think you have genital warts or any type of STD, GO TO THE DOCTOR. Coming on here and repeatedly posting looking for ways to get out of it isn't going to help. You've got something wrong, find out what it is, professionally.
And you may be worrying yourself for nothing. The only way to know for sure is to have the doc look at it, and in the case of sores down there, the doc has to check them while they're still there. 'Hoping they go away' is the main reason some STDs spread so well. There are some that have one temporary symptom which disappears, leaving the person thinking "hey, it's gone, I'm fine" while in fact they are now just past that stage, but still very infected. Don't be one of those people.
All that said, in answer to this specific question, it is very unusual for warts to disappear after only a few days. They typically last for months, years even, if not treated. They tend to go away after about two years, for some reason, if left untreated, NOT a few days.
The warts go away?
