Endometriomas don't shrink. It will have to be removed surgically. If you have an Endometrioma that is a good indicator that you have moderate to severe disease and you want to get it all out.
It's a blood cyst. I hope it shrinks when I go back with the birth control. but if it doesnt can they drain it?
Okay so I responded to you through message but I didn't know you had a cyst. What type of cyst is it? A functional cyst? Endometrioma?
