Hi,
You don't say what your age is but cysts are very , very common in younger women. It probably isn't so much that your cyst "spread".. but that you have another one. If you check out the top right of this page, it will explain a lot about cysts. Again, they are very very common in younger (pre menopausal) women. Many times they will simply disappear on their own. Other times they will grow and have to be removed surgically. 95% of them are benign..
You really do need to see your Dr. I hope he or she is a Gynecologist..
Take care,
Sandy
It's hard to say what to do for the pain if you don't know exactly what you are dealing with.......... I hope you can see a Dr soon and get some answers.
