My lips have been itching and burning for 4 months. i recently found bumps inside my lower lip. i dont know whats happening to me, please help?

Itching and burning lips and lesions are commonly caused by allergic reaction. If you wear lipstick, stop doing for a couple days and observe the symptoms. If not, pay attention to the symptoms after you eat something. A whole fruit is a common offender if you eat the intact skin (contaminated with spermicides or preservatives). Wash fruits and peel skin off. New med can do the same as foods.
