The “booger” may be a nasal polyp or a foreign body, since kids place a variety of things in their ears and nose, with associated infection. If the doctor is unable to remove this “object” or if it turns out to be an abscess, it may have to be surgically excised.
Hope this got resolved.
You don't think that she may have stuck a piece of meat up her nose, do you? Or some type of bug? Just suggestions, but definately get her to a doctor. Perhaps an ENT. Please let me know what happens. BTW, how long has she had this?
Sincerely,
