I've dealt with Bartholin Cysts for years now. I only get them on one side, the left side. It is very easy for me to relieve them and I hope this will work for you too if you get Bartholin Cysts.
Just use your fingers to locate the "grape-like" cyst.
(You can lay down or sit on the toilet to do this. Perhaps taking one of those sitz baths before hand will help too, but I have never had to do that part.)
Take one or more fingers and press on the "grape-like" ball till it's holding still and secure, then continue to slowly press a bit harder, keeping constant pressure on it.
Then, increase your pressure on it till you feel this little teeny tiny sting inside your labia (you have success when you feel that!)........and then suddenly all of this clear mucousy liquid will come pouring out (it is the same stuff that you see when you have sex and your body lubricates itself when you get wet), but keep your pressure on the "grape" and walk your fingers over it to make sure you have gotten all of the liquid out. FYI....Sorry to be graphic, just want to help anyone out there with this issue.....but it is so easy to press on your Bartholin cyst to release the liquid inside, even my boyfriend has learned how to press on it and the extra lubrication that comes out is helpful for sex. Not trying to gross anyone out, just saying how easy, helpful and useful this remedy is!!!
If you still feel a little bump in there afterwards, do another round of the stabilizing with the fingers and then put the pressure on. You may feel like there is still a tiny (about the size of a pea) bump after you release the liquid, but I find that sized one can usually go away on it's own after I do this at home remedy.
This technique works great for me for several years, Hope this can help someone else out there! Good luck!
PS, I never had any type of infection that had strange foul odor, nor any type of strangely colored or bloody secrection. If you do have anything remotely different than clear odorless liquid... then you REALLY need to see your doctor.
