There is a rough patch on my top lip and i feel it when i lick my top lip. it wont go away. my top lip feels and looks so weird now. what should i do?

If not a cold sore..: Some roughness and mild redness on a lip can be lip eczema, which may be treated like skin eczema, using hydrocortisone cream (twice a day for 1 week) plus Vaseline or Aquaphor to retain moisture. Sometimes lip balm or lip sunscreen chemicals cause an allergic reaction. Other times a person is a primary lip-licker (it's his habit). Once cracked, lips can get irritated by routine foods and juices.
