Welcome to our Forum. The topic of HPV and genital warts is a complex one. The question you ask is one that we have had a number of times in the past. I will try to provide some facts. For additional information on this most common of STDs, I would suggest search for other HPV- and wart-related Q&A on this site, as well seeking addition information on sites such as the American Social health Association web-site (disclosure, Dr. Handsfield and I are both on the Board of ASHA).
Once HPV has been successfully treated, the recurrence rate is about 20% with nearly all recurrences occurring within a month or, at the outside, two following resolution. If you choose to seek the opinion of your doctor, I suggest that you have the same person who initially treated you take a look. Given your past experience I suspect you are far more vigilant regarding the possibility of HPV than persons who have not had HPV. In addition, when closely inspected there are many irregularities and "bumps" which can be confused with recurrent warts. When warts recur, they do grow so if the bumps you note are not changing, it is most unlikely that they represent HPV infection. In the vast majority of cases, once warts have resolved, either spontaneously or with therapy if there is no obvious recurrence in 2-3 months following clearance, there is very little chance of recurrence or transmission to sexual partners.
In addition, this might be a good time to consider the HPV vaccine. It is highly effective and that you have had warts in the past does not mean that it will not be helpful to you. Hope this helps. Take care. EWH
