What's the cause?: This doesn't happen unless there is an underlying problem -- do you know what this is? An infection in an embryonic remnant, which some folks still have here, may be remarkably difficult to treat -- has imaging with contrast been done? There's no guessing without a full examination of your microbiology results what antibiotic to use, and surgery may be your best hope. Good luck.

French GreenClay: Study of French Green Clay found that this causes inhibition of bacterial and microbial growth and helps heal wound faster. So use locally combination of french green clay and neem oils to heal the wounds. After healing use Moringa oils with castor oils to strengthen scar tissue. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2600539/
