My left labia is very swollen and hard to the touch in parts along with being very painful. There is also a slight odor. My Dr. said it was a vaginal infection, not a cyst like I thought. I am going on my 3rd day of antibiotics but the swelling has not gone down and it is still very painful. The odor has gone away but I am wondering if the antibiotics are working and is it normal to take this long for any relief and decrease of swelling?
