On Mouth Ailments

So my mouth has been bothering me for a couple days now, and this morning, since it hurt so bad and looked so gross, I decided to go in to the college nurse and ask about it. I was given an appointment for 20 past 11, was there on time, waited half an hour before being seen, and then spent about 5 minutes in the office. Her verdict: I either have a) a fungal infection, b) a bacterial infection, or c) gingivitis. As you can imagine, I was thrilled. I was sent (through the pouring rain, mind you) to the university pharmacy where I picked up a cream that I'm now to use three times daily (2cm applied and brushed for 1-2min each time) for a month. She didn't seem overly concerned so I'm thinking it's not terrible, though I'm too afraid to look into it. Better not to know and simply get better I'd say. In the mean time I've to put up with the general acheyness in my teeth and gums, and for an unspecified time period. I'm hoping it's short.
