thanks Trillian - me too! I think he has been suffering - as it is slightly itchy and I noticed some behavioural change (negative) about a month ago but maybe that could have been his second year molars....

Just to clarify, it's not ring-worm, or worms.... but it's a funny looking pimple that has been moving eastwards in an up-down fashion, about 3 cm over the past two months. It's a fast-moving bugga' and I'm surprised that it has survived this long (if it is what the paediatrician says it is).
