Is any of this happening?
Be seen today
Seek urgent medical assessment for fever, chills, vomiting, significant lower abdominal or pelvic pain, or rapidly worsening swelling.
These are not typical features of a straightforward yeast infection and may have another cause.
And for anyone, someone who:
has a fever with a stiff neck, a rash that does not fade under pressure, or severe headache
has a wound that is hot, spreading red, or leaking pus
