Heads up: If you have a vagina, you could end up with blocked glands or pimples in your vagina.
The Bartholin glands are what lube up your vagina. Sometimes, they get blocked, and you can end up with a Bartholin cyst. Please note, that horrific Mayo Clinic illustration is not representative to actual cyst size in most cases. Some of them are so small, you don't even notice it, and they clear on their own.
Others are large enough you can feel them and they get painful. There's some real easy home treatments you can do to help unblock the gland and clear the cyst:
Epsom salt bath. Just do a nice epsom soak as you would for sore muscles. If you can stand to touch the cyst, massage gently around the edges of it. Don't squeeze on it. Just gentle massage on the edges to encourage movement.
You can also wet a washcloth in warm water and press it against the cyst. You can massage through the washcloth if you need to. Re-wet and press to the cyst a few times in a row.
You may need to repeat option #1 and option #2 a few times before the cyst goes away.
If it hurts too much to sit or walk or touch, ignore steps 1 and 2 and get to your doctor. They may give you this same advice, but they may also be able to drain it if it's in bad shape.
Vaginal pimples are basically the same, except they can get a head on them. Go with options 1 and 2 again. Do not put anything on the pimple. Odds are, you won't be able to tell if it's a cyst or a pimple unless you know the exact location of your bartholin glands.
If they seem to happen regularly or a lot, definitely talk to a doctor about it. Hormone levels--unshockingly--can affect them.
It's okay if you think it's gross. You don't gotta think everything your body does is super rad. I think they're super gross, but it's also nice to know how to deal with them because it just makes it easier to deal with them.
