How long until my swollen and bruised labia goes back to normal? I m not sure if this is the right place to ask but about a week and a half ago I had some really rough sex. I didnt notice pain during, but shortly after I experienced mild discomfort and my partner noticed swelling. Once I got home hours later my right labia was swollen to the point it reached my left thigh, and the pain was unberable to the point where I could barely sleep. The next morning my right labia was literally black from bruising. Now swelling has gone down significantly but is still noticably larger than normal, and painful. Bruising has mostly subsided. I am sure I did not get an STD or infection, the swelling was due to rough sex.
