But of those who had complaints, six in 10 suffered from chronic problems. And although many had suffered from unpleasant itching or swelling for years, few had bothered to get their problems checked by a doctor, the researchers found.
Of the ones who reported problems, how many had 'unpleasant itching' or the like as their issue, and how many of those didn't bother to see a doctor? If we were to assume healthy individuals, taking normal precautions, doing normal aftercare, going to a place that seems safe/hygienic, and then going to a doctor if a problem arises: in such cases how many have had long term problems? In any event, I'm glad the article is out there though, so hopefully people think about these things before making a decision and getting one done.
