try not to stress out, it could be as simple as a little zit. i always get those in the corner of my mouth and they hurt so bad. as for the little white bumps, those could also be an acne outbreak. if it doesn't clear up within a few days, consult your doctor.
Well the red place on the corner seems to be getting better since it poped even though it wasn't a bump at all.. & i woke up this morning & those little white bumps were gone... yesterday my whole body was itchy i had used a new perfume cold this been a allergic reaction to something? everything were itchy but my lips my lips i noticed were a little red and swollen now my lips are normal and the white bumps are gone along with my body itching.
