nolse,
I seriously doubt you injured your eardrum.
you probably irritated the gland in your ear that produces cebum (earwax). earwak starts out as a pretty slippery clear fluid, and only turns yellow/orange after quite some time. i would carefully monitor your ear for any change for the worse or if the condition does not change. the thing i would worry about is infection, called otitis media. one of the cardinal signs of this is pain when you pull up and out on your external ear. if this smarts, go seek help. otherwise, it'll clear up and see a doctor if you think your hearing is altered or an infection takes hold. if you have time and money, then see a doctor now. otherwise, odds are it's only a flesh wound.
