My son was recently scratched on the face by a dog. Most of the scratches were superficial and have already healed to nonexistence, but there were two deep, puncture-like spots on his cheek. It has been a week since the incident happened and the spots are light pink and seem to be healing very nicely, but there is a very hard knot under the skin under the two puncture spots. It does not seem to bother him when I touch the knot and it is most definitely not warm or red. He has had a low grad fever, but he is also cutting teeth. I worry if I let it go too long it may have to be lanced, and being that it s on his face I would rather it not come to that. We will be lucky if he comes out of the dog scratch without a scar. What could this hard spot be? And should I make an appointment to see his pediatrician?
