Ok so I don't get my period every month I don't even get it often but I got it this month and it has been crazy pain. At first it was just my lower back killing me and heavy flow bleeding but today It started itching and when I went in the bathroom my right Virgina lip is swollen .I touch it to see if I felt anything and I feel like a ball under the skin. I don't see any red bumps or anything above the skin like I do sometimes when I shave. Is there something wrong with me? Should I see a doctor?
