Just recently my male has developed sores as well. They are dry and not wet or infected looking. In fact they look somewhat like what a lizard would have if he banged his face into the side of the tank. I have however never seen him do this. they heal quickly on their own and i never need to put any antibiotic on them. I'm not sure if i should go to the vet or not because of the non infective nature of the sores. i wish i could help you but i seem to have the same problem and only with my male as well.
