My big toe is infected. What will the Doctor likely do when I go tomorrow?

[I am Hashem!!]

I am a bit worried. I think my toe became infected as a result of me biting my toe nails. I was really stressed during finals, and don't know what I was thinking. My one toe is very swollen, though it is not oozing. I soaked it in hot water, which calmed it down temporarily, as well as some anti-inflammation powder, which helped for about 10-20 minutes. Is this likely to be something serious? What symptoms should I look for to determine if it is something serious
