Most of us here never used bite our lips or lick them,mine started when i scratched below my lips.my lips started to swell n i though it was some kind of an allergy but it wasnt i have never been allergic.after various test it was confirmed that its not allergy.i knew i had sd but never thought the two were related,like i mentioned in my previous post when i visited my dr in connection to the dandruff that has been falling of my beard he said there is chance that the two could be related.I believe there were a lot of people who related sd and ec in this forum before,i really hoped those guys who show up again.
