Hello, my urethral opening is swollen. This is giving me extreme amounts of pain when I walk or even sit a certain way. Ive also experienced sharp pains coming from my abdominal area. Ive recently started a new birth control pill and I wonder if I am getting these symptoms because of it. It doesn't hurt when I urinate and I do not have any strange discharge. Ive recently been tested for sti's and std's and all of my results came back negative.
