What does it feel like when a cyst bursts?!

What does it feel like when a cyst bursts?

I'm really scared cause I don't know what this is. I know someone's going to say call the doctor, and I did and I got my usual response from the nurse of go to the er (she says to do that about everything though, so I need another opinion).
Last night whenever I sat down I got this really bad pain in my right pelvic side (too low for appendix). It would go away whenever I stood up, and walked around for a little bit. This morning, it's just a nagging pain like I've had before (I've had cysts, and I have endometriosis), but I'm still really scared. So I'm wondering what it feels like when a cyst bursts and could that have been the pain I felt last night?
Please help, any answers would be wonderful.

i had one of those last summer and it hurt sooo much! i play hockey and NEVER cry but when it burst for the first few days i cried like every night. for some reason when i was out walking around, i needed to sit down. its like having your period but 10x worse. good luck with it. just start taking some pain killers now. it will help for the future
