My daughter had a sore throat. After a day or two, we noticed that it had white spots in it.
We took her to the doctor and he said it wasn't anything treatable, but she's better in a day or so.
Considering that sore throats run their course in 3-4 days, shouldn't we have taken her to the doctor sooner -- or even before she got sick? ;^)
It's seems somewhat like this: Take the medicine and be better in a week or let the malady run its course over 7 days...
