These guidelines are based on a combination or vast professional experience, common sense, research. This is not to be considered a substitute for medical advice from a doctor. Be aware, however, that many doctors and dentists do not have specific training or experience regarding tattooing and piercing, and may not be educated on how to best assist you. IF you do get an infection, the jewelry should be left in so that the infection may drain. If the jewelry is removed the hole may close and result in an abscess. Always contact your tattoo artist or piercer if anything seems abnormal or if you have any concerns.
