This should be seen by an ENT doc. Likely, it is just a dermoid cyst or something benign like that and can very easily be handled in the office. Left alone, these can get infected and be rather painful (and make excision a little more challenging). Rarer and scarier things are possible, however.
I just called to relay your response, and he informed me that last night he messed with it, and pus, then blood drained out. Does that mean anything to you, or is he going to be okay? He seems to be done worrying about it. :(
No, he'll probably be OK. Again, if it's a cyst, it's just a matter of time before it fills up again. If it was just a little abscess (I figured that it should look a little angrier if it was, and it kind of didn't in the picture), that might be the end of it.
