Not being able to see the wound, I recommend an Epsom salt foot soak a few times a day to draw out the infection. Moist wounds heal faster so keeping something like neosporin on it will help. I learned years ago that before the advent of Neosporin, the remedy was raw honey. I keep raw honey (manukka) if I can find it. It is interesting because the exudate from the wound mixes with the honey and the reaction creates hydrogen peroxide (H2O2). Honey has been proven to have antimicrobial properties. There is some process with the honey that binds the oxygen free radicals produced by the H2O2 reaction and the antioxidant effect of the honey neutralizes them.
Sounds crazy? Significant research has demonstrated the efficacy of raw honey (and specifically that honey from the manuka blossom) and it's healing properties and also more importantly it's effectiveness in the healing of wounds infected with a drug resistant strain of bacteria called Methicillin Resistant Staphlococcus Aureus -MRSA. Many hospitals have begun to use wound dressings impregnated with manuka honey.
Should you go to the doc? None of us could say...post a pic and that will help the internet diagnosis.
As an aside-
The best remedy for sore throat discomfort-1tsp raw honey, tsp apple cider vinegar(the cloudy kind like Braggs) and 1 tsp hot water.....gargle for 30 seconds and repeat..aaaaah, instant relief plus there are the healing properties of honey coating the back of your throat.
