If this is a fungal infection, the infection feels/appears quite “deep rooted.” Since fungal
infection can be worsened by topical steroids, I would first like to rule out
yeast infection, or at least try an oral medication, although I know those are bad for the liver. Should I ask for a culture? Any ideas? Thank you for reading.
