HPV can stay in your body for years with no signs.. Your case sounds about right, but we aren't doctors who can diagnos so make sure you check in! Treating them is not hard, you'll probably get a cream that you have to apply (aldara) and there are other options for wart removal.. most importantly, get a pap to make sure there have been no changes to your cervix.. if you have warts, there's a good possibility you have other strains of hpv which are dangerous to your body (your cervix is it's first target) and you want to make sure you are safe from that.. If you have hpv, you'll want to take immediate action by making sure you know which ways it is impacting you and which ways it isnt.. If you know you only have hpv warts, make sure you get the vaccine for HPV which protects against the cancer causing strains of hpv!
Hope this helps.
