Alright Nico, FINALLY I have time to write that post I promised. My apologies for the delay (you know why I was delayed).
I've had four cysts. My first one happened when I was 19 or 20. The next two came soon after that. The fourth one was quite recently - it (mostly) disappeared just before Easter.
The top three circles I've drawn on this picture show the locations (approximate) of the first three. The bottom filled in circle shows the location of the most recent one. Note - the picture is NOT of me!!! It was borrowed (pinched really, coz it's not as though I'm giving back something in return) from Wikipedia. All of them were actually inside the outer lips, but I couldn't be bothered searching for a pic that would allow me to show it more accurately.

So, when the first one appeared, it hurt like all fuck. Went to see a doctor. He said they usually disappear by themselves. I told him I was in agony, and that surely he could do something about it. He said 'No, at this point I can't'. Apparently, Australian doctors don't like to lance them, because they almost always come back (personally, I think it's worth it, for the temporary pain relief, and on the off chance that it will be permanent). He would only do surgery on it if it went for a particularly long time AND if it was particularly painful and preventing me from living life normally. However, he also said that it was almost at that point.
He suggested all the usual remedies (hot compresses etc). But he also said 'I'm not really supposed to say this, but squeezing (popping it from the inside, not towards the outside) often seems to help, and it might be the only thing that stops you from needing surgery on it, as it hasn't gone away by itself yet'.
His other highly useful piece of info - I'd gotten it from masturbating too hard :redface::redface::redface:. Not that he put it that way. He actually said 'They can sometimes be a result of too much pressure placed on the area'. Well, I've always been a fan of over-stimulation, and my favourite technique at that time was rubbing my clit and surrounding areas REALLY, REALLY hard with a vibrator. So that looked to be the cause. Cue extreme embarrassment :redface::redface::redface:.
So, in an attempt to avoid surgery, I went home and I squeezed the fuck out of it. It fucking hurt. I can't describe how much it fucking hurt. I screamed (and apparently I have a high pain tolerance). But it got rid of it!!!! :biggrin1::biggrin1::biggrin1: I actually felt the fucker burst and start draining. Within a day or two the pain was completely gone and all was good again.
Over the next year or so I got another two. Didn't bother going to the doctor's and got rid of them in the same way (this time BEFORE they got to the immense agony stage). After I got the third one, I decided it was time to change my masturbation habits because my current method was obviously not doing me any good (yes, it took three cysts before I gave in and changed it :redface

. Now I get my over-stimulation by using several toys at once, instead of by extreme pressure. Once I changed from the extreme pressure method I didn't get another cyst until recently.
The cause of the most recent one was a bit more ambiguous. I don't use toys in that area, so it didn't share a cause with my past ones. I DID end up going to the doctor for this one, because after a week or two it still hadn't disappeared, and I'd been squeezing it on and off since day 1. She said it was just one of those thing (ie. I don't know what the hell caused it). She gave me antibiotics, just in case, and said I'd just have to wait patiently for it to disappear.
Fuck that!!!! I ended up attacking it with a needle I had leftover from injecting (medicinal) drugs last year. I got rid of the medication inside it first, then lay down with a roll of paper towel (in case I hit a blood vessel and my warfarin made me bleed to death), and some alcohol wipes, and poked the needle in as far as I dared. Two days of needle poking seemed to get rid of the bulk of the liquid. There was only a tiny little core left that I couldn't get to (about the size of a pea), and once the bulk of it was gone even the core started to drain and disappear by itself. I ended up having the horrible thing for a month or so all up and I DON'T want another one again. Ever.
