There are many causes of vaginal blisters, most of which can be avoided with proper nutrition, practicing safe sex, and good hygiene. The most common causes of vaginal blisters are infections and sexually transmitted diseases (STDs). They can also be caused by poor nutrition, stress, clothing, and some recreational activities.
Blisters can develop on the vagina due to a bacterial or fungal infection. These infections can develop from wearing bathing suits or synthetic undergarments. The warm, moist environment that these items form can create a breeding ground for bacteria and fungus, which can cause vaginal blisters to form. Using pools or hot tubs that do not have the proper ratio of chemicals can also cause infections, and therefore blisters, to emerge.
STDs are one of the leading causes of vaginal blisters, especially genital herpes. This disorder causes groupings of blisters to form on and around the vagina; they are usually very painful and often burst and crust over. Herpes can be prevented by practicing safe sex, although it is not curable once it is contracted. Some medicines can be taken to reduce the amount of vaginal blisters and limit the possibility of transmission to a sexual partner.
Poor nutrition and tension can also cause vaginal blisters. When the body lacks the nutrients it needs or is creating large amounts of the hormones that go with stress, it can respond in strange ways; this may include developing blisters on the vagina. When a vaginal blister is caused by lack of nutrients or stress, it is usually just a single blister that is only painful when touched.
Certain types of underwear can also cause blisters on the vagina; tight jeans or pants especially when worn without undergarments can do the same. While many women love lacy panties, it is important to make sure that the crotch area is made of a breathable fabric such as cotton. Synthetic undergarments can trap moisture against the vagina, causing sores, or irritate the sensitive skin, also causing blisters. The same is true for tight pants. The friction caused by walking in tight pants can irritate the skin, resulting in the formation of blisters, much like the blisters that form on the back of the heels.
Some activities, especially horseback riding and bike riding, can also cause this condition. Much like the problem with clothing, these hobbies can create a great deal of friction in the vaginal area. To prevent blisters from developing when doing these activities, wear breathable clothing and items that are thick enough to reduce some of the chafing.
By wearing breathable clothing, taking care of themselves, and limiting the chances for infection, women can reduce their chances of developing blisters in this sensitive area. If they do develop, schedule an exam with a doctor to find out about the underlying cause of the blisters or sores. This can allow for the earliest and best treatment of the condition.
