It's possible you might even have adhesions in addition to PCOS (if, in fact, you do have that)... adhesions are scar tissue, after all, and they are the body's natural healing process... except that in some people they form excessively. They commonly cause "pulling" pains, and your history certainly shows that they could be there.
Ask your doctors... or your surgeons for all your surgical reports and see if adhesions are listed anywhere. They would have been seen during surgery and MIGHT even be the scar tissue on the ovaries. In fact, adhesions commonly are caused by the "foreign" fluid that comes out of a ruptured ovarian cyst. Adhesions will not be seen on any test... they can only be verified by direct visualization (like during surgery).
My story with adhesions is here if you care to search for it.
Wishing you a painfree day...
