I'm only calling this the worst because I was young enough for my other procedures that I don't fully remember the pain.
I developed a cyst on my labia. Not a bartholyn for those with experience, higher up. I was doing the warm compress thing but it wasn't helping. Within a matter of hours it went from the size of a pea to the size of a golf ball. Obviously I had to go get that dealt with.
You'd think the cutting me open and draining it part would be pretty bad. Or even the healing. Nope. Local anesthetic to the labia was absolutely the worst pain I can remember feeling. And I got my finger stuck between two gears one time.
The 3 minutes or so of agonizing, burning pain lasted longer than the time it took them to cut me, drain it, and pack it. My husband had bruises from me gripping him so hard and was bleeding from involuntary nails digging in.
Shockingly I didn't even take any of the pain killers they gave me for recovery. By the time the numbness wore off there was no pain left. Trying to pee after was another story. Thank god for the invention of a Peri bottle.
But yeah, felt like someone set my labia on fire while also stabbing me with a knife. 0/10
