Is there any protocol or approach to wound care that would preclude using an oral antibiotic for an infected wound? My wound clinic/plastic surgeon will not prescribe anything for the chronic ischial wound I have which has an odor, slight pain, brown, khaki colored exudate in the wound vac canister. They won't do wound culture either, which I s pecifically requested. Upset, not sure what to do. No fever, chills, temp etc.
