both corners of my lips are just cracked. they pain me so much. this kind of illness is called "kohkakuen" in japanese. i just took the japanese-english dictionary and found it's called "perleche" in english. perl-ech-e, perl? ech! e. huh. just a fun.

http://www.ncemi.org/cse/cse0409.htm told me that i was wrong. i believed this perleche is happened by lack of nutrition such as vitamine. ah again, i was totally wrong. i'll go to a hospital.
