Summarize this article:

Fill the sitz bath with warm water and place it over the toilet. This will allow you to sit and soak just your genital area. Add 1 to 2 tablespoons of epsom salts in the water and stir the mixture till the salts dissolve. Sit on the bath for 10 to 20 minutes, twice a day. You should do sitz baths three or four days or till the cyst improves. You can buy a sitz bath at a pharmacy or medical supply store. If you don't have a sitz bath, you could also just run a few inches of water in your bathtub. More research is needed, but ACV can be used to try to reduce the size and swelling of vaginal cysts. Either run a sitz bath and add 1 cup of ACV or you can soak a cotton ball or swab with ACV. Apply the soaked cotton ball or swab directly to the cyst and hold it there for 30 minutes twice a day until you notice swelling reduce. While ACV is a popular home remedy, scientists caution against relying on vinegar as a medicinal treatment. Fill a hot water bottle with hot water and wrap it in a clean towel. Place this against the cyst to provide some pain relief. You might also try applying a heat pack, so long as you keep another cloth between the pack and your skin. Take care not to burn the delicate tissue in the vaginal area. You can also dip a flannel or cotton cloth in hot water, wring the water out, and apply it directly against the cyst. Mix 1 to 2 tablespoons of aloe vera gel with 1/4 to 1/2 teaspoon of turmeric powder. Stir until the mixture forms a paste. Use a cotton ball, tampon, or swab to apply the mixture to the cyst. Leave it on for 20 to 30 minutes once a day. Don't rinse or clean off the paste. Just let it run out naturally.  You may want to wear a sanitary napkin so that the bright turmeric doesn't stain your clothing. Studies have shown that turmeric (curcumin) is an anti-inflammatory. This can reduce the irritation caused by vaginal cysts. Since it may take a few days for the cyst to clear up, you may want to take OTC pain relievers like ibuprofen or acetaminophen. If you feel severe pain that doesn't go away after taking OTC medications, contact your doctor. Always follow the manufacturer's instructions regarding dosage and how often to take the medication. Never rub the cyst, even when cleaning or washing the area. Gentle soaks in the sitz bath or tub are enough to keep the area clean. You should never douche. Douching is unnecessary, can irritate the cyst, and is considered to be harmful to women's health in general. Since you'll want to avoid irritating the cyst, consider using a sanitary napkin instead of a tampon, if you're menstruating.
Soak in a sitz bath. Use an apple cider vinegar (ACV) soak. Use a warm compress. Apply an aloe vera mixture. Take over-the-counter (OTC) pain relievers. Avoid irritating the cyst.
