If he is not moving and not eating the area has probably become infected. That is the problem with injuries such as these- they can easily get secondary bacteria and turn septic. I would treat with kanamycin- active ingredient in Seachem Kanaplex. You will need to change at least 25-50% water before each dose to keep the tank low in organics so that the medication isn't offset by organics in water.
