Not to fret in most cases it will heal just fine. Like all wounds: keep it clean, neosporin is good. Watch out for a distinct odor, puss, bubbles - the typical stuff you look for when you get a scratch or cut.
Also, can you post a picture that way we can see "how bad it looks" and where it is located? This will allow those that have a lot more experience take a look and get their opinion.
