There are various different causes of itchy burning skin and so to make a diagnosis would require medial advice. However, some of the common diseases/causes are dermatitis, eczema, and allergic reactions.
If you get pepper spray on your lips, it will feel like like your lips are burning. Wash your lips well, but gently, and then wipe gently with milk on a wash cloth or hold the wash cloth to your lips. The milk will help to "neutralize" the effect. An even better remedy if you have them on hand is banana, just smear some on your lips and wipe off when the burning stops, it works quickly and well when your mouth or lips are burning from the capsaicin in the chile.
