My Lips Are Severely Chapped. I Am A Runner So

my lips are severely chapped. i am a runner so i know i have been outside a lot but have used lip balm. i try to drink more water so i do not think it is dehydration tips. my husband says i have bluish and purplish spots at times and my mouth is a tiny bit swollen. other than the lip balm, water.. any ideas? i am a critical care nurse now working in a surgical center so i know this is not cyanosis.
