I have a purple, blueish discoloration under my lip area. When I ate a nectarene, my lips started an inflammation, which turned me red, then my bottom lip turned purple in June 2011. I went to an allergy specialist who couldn t tell me the cause. Then I went to a spa medical doctor for profractional laser treatments and it hasn t really improved the discoloration. I am a light skinned African American female in her 20s. Both deemed to fail. Do I have a baterial or fungus infection deep in my pores? I am going to see a dermatologist to get another opinion. What should I ask?
