The Past Week I Have Been Feeling Pain And Burning

The past week I have been feeling pain and burning on my vagina lips. Itching and burning and sore to walk I don't know what's going on. And I noticed today after work the right lip is swollen 2 times the sizes of the right lip and there is a bump the size of if you were to take Styrofoam apart the little white ball on the lip. And there is no fluid its just hard someone please help. I've had clhymidia in the past but got treated and it went away is this another disease ? Also the opening to my vagina if very swollen
