What if the doctor did not find the lost tampon inside of you?

If the emergency room doctor did an effective speculum exam, then the doctor w2ould not be able to miss a tampon in your vagina. There is nowhere else a tampon can go; the vagina is a dead end. But removal of a lost tampon is not a reason for an emergency room visit. Next time, see your regular health care provider or your local family planning agency. They are better able to provide this kind of care. Routine GYN care is not what emergency rooms are for, and not their specialty.
