Swollen labia (my right side) with painful and very large bump above the clitoris. what is it? sore.

Insect Bite?: Without a photo, these are always difficult questions to answer. The fact that the swelling is only on one side, makes the idea of a bite more likely. Of course, one always needs to consider a std if you are sexually active. If you're worried or in a lot of pain, you can go to urgent care now or see a gynecologist tomorrow morning.

Infection: Pain and swelling in the genital area is probably an infection. The most likely cause in a sexually active woman is herpes. You should be checked soon so appropriate treatment and accurate diagnosis given.
