One possible cause for burning lips after drinking orange juice is a condition called burning mouth syndrome, according to a study conducted by the Orofacial Pain and Oral Medicine Center at the University of Southern California School of Dentistry. It also causes a loss of taste.
The burning sensation of BMS can be felt in the mouth and on the lips, notes the study, Acidic foods, such as orange juice and tomatoes, can cause the symptoms of BMS to flare up. BMS is typically separated into primary and secondary categories. With primary BMS, the burning sensation and other symptoms occur due to some oral irritation. In the case of secondary BMS, symptoms also indicate other clinical problems or diseases.
BMS is more common in women over the age of 30 and men over the age of 40, notes the study. For women, the condition normally occurs within several years after the onset of menopause and is often associated with systemic diseases. BMS is usually treated with prescription medications, which relieve pain and suppress the condition. BMS is a neurological disorder, and while primary BMS has no cure as of 2015, people suffering from BMS do not normally find relief without medical intervention.
