In my case, it strictly occurs when I take certain
birth control pills (
Yaz, Diane35) but not with others (Alesse). Also, it appears within 24 hours of taking the first pill, persisting until 24 hours after the last birthcontrol pill and disappears as soon as I am not taking the birth control pills. Obviously, it is a side effect of the hormones in certain birth control pills.
Also, Fibrocystic disease is usually found in women over 30.
