There are many conditions and types of injury that have the potential to cause vaginal swelling. Among the most common are trauma to the vaginal area during sexual intercourse and injury that results from a blow to the area. Some women may also develop this swelling after childbirth, regardless of whether they have vaginal births or Cesarean sections (C-sections). Vaginal infections, including yeast infections and sexually transmitted diseases (STDs) may also cause swelling in some cases. Additionally, exposure to harsh, irritating chemicals in the form of soaps, detergents, bubble baths, and even scented feminine products can cause the problem or help to make it worse.
One of the most common causes of vaginal swelling is some type of trauma. For example, a woman may experience swelling in the vaginal area after particularly rough sexual intercourse or even after having sex without enough lubrication. A woman may also have swelling after an injury, such as a blow to the vagina. Some women may also notice swelling in this area if the vagina is injured or irritated while riding a horse or dancing.
Sometimes women also experience vaginal swelling after childbirth. The movement of a baby through the birth canal can prove traumatic for vaginal tissues, and some women experience swelling in this area that lasts for several days. Likewise, a woman may experience soreness in the area after having a baby. Interestingly, a woman may also experience swelling after a C-section. This can be due to hormonal changes, pressure exerted during labor, unsuccessful pushing attempts, or attempts at assisted vaginal delivery before deciding on a C-section.
Vaginal infections are also among the most common causes of swelling. For example, itching and swelling are common symptoms among women who have vaginal yeast infections. A woman may also experience swelling in the vaginal area after developing a bacterial infection. STDs are also among the most common causes of swelling and irritation.
Chemicals can sometimes cause swelling of the vagina as well. For example, a woman may experience vaginal irritation after using a new laundry detergent or a new body soap. Some women also find bubble baths, scented maxi pads, and tampons irritating. A woman may even find that spermicides and lubricated condoms either cause irritation and swelling or contribute to the problem. Once irritation and swelling have developed, however, something as simple as wiping with abrasive toilet paper or wearing overly tight underwear may make matters worse.
