Was this an actual doctor or a trainer?I've seen plenty of trainers who are very knowledgeable on skin conditions but have also seen a lot that have no clue. The fact that they had you wrap it makes me wonder since simply covering it will not prevent spreading to others and also keeps dried and healed spots moist.. So, by covering it you probably kept the spot from drying up or staying dried up. So when the official asked to see it, it probably looked moist and still active because it had been under the wrap all day and not dried up thus making it appear active. Its unfortunate that your wrestler couldn't finish his tournament but in a situation like this the official does have the authority if he thinks the skin condition is active. Perhaps you can post a pic of the spot. This site could be a good place to educate people on skin conditions and prevention. Maybe Joe could create a section with pictures to help people better recognize whether something is a skin condition or simply a blemish.
