For the past few weeks, I have had this sort of 'film' over a part of my lips..sometimes when I wake up, the top lip seems swollen. I am a faithful user of petroleum vaseline on my lips and chapstick during the day so I cannot imagine that this is due to dryness! It seems that my lips are dry and sort of peely..only around the outer part of my lips and especially the top lip..not sure how to describe it. But here is the odd thing, when I eat foods with sauces..it stings my lips so I know that the peely thing happening must be like an open wound for it to sting (though its not bleeding or anything close to it). I've read the forums on this site and don't see anything similar. Can anyone provide advice?
