But are the sores caused by bacteria? Or are the aintibiotics as a precaution to ward off the bacteria that may make the sores worse?
Open sores no matter the root cause are open to infection. Therefore the administration of antibiotics would be pro-active, rather than preventative on existing sores, and preventative on any that may occur in the near future while attempting to determine the root cause of the sores. Hopefully the specialist will be able to shift quickly through the smorgasborg of possible skin problems for Max.
