2 days ago my upper lip on the right side got swollen and numb. I took some Benadryl for a day and the lip went back to normal. About an hour ago my bottom lip on the right side started to swell up a little and it is feeling numb as well.. Do you think this is an allergy of some kind. If so could it be food or some pollutant in the air? Your feedback is appreciated.Regards,Ann
HIT hank for asking to ChatDoctorThis could be contact allergy and a bit difficult to know it, the long acting anti-histamine is the best Chat Doctor.
