You learned about a cyst last week and they are recommending hysterectomy? There must be a bit more going on than a cyst. Normally the first step is to remove the cyst (sometimes the ovary/tube as well) and nothinig else unless there's a real reason for it. You are really young yet!
My doctor has me coming back November 19 and he wants to a hysterectomy Laparscopic hysterectomy but i don't know if he is going to do a complete hysterectomy or not that is why i go back to him on the November the 19 and he will let me know if he is going to do a full hysterectomy or a partial hysterectomy.
A cyst can twist the tube/ovary and cause torsion. If you think the pain is beyond bearable, beyond the worst menstrual cramps imaginable, it could mean a need to visit an ER. It is considered an emergency if twisting is severe enough to cut off blood supply to the area, requiring emergency surgery.
Many times, the pain episode is a temporary one, not an emergency but definitely unpleasant. Do you know the size/type of the cyst and what the doctor has recommended be done about it? Sometimes surgical removal is the best solution while other times it is OK to just wait for it to resolve on its own.
It is also painful if the cyst ruptures, although most of the time the body can heal on its own as this is one of the ways cysts resolve themselves (infection is one possible side effect while the body works to reabsorb the remnants of a cyst).
