If you have adenomyosis and you used to have dysmenorrhea and then you do not have dysmenorrhea, it is possible that the dysmenorrhea is not due to adenomyosis. Adenomyosis is clinically asymptomatic in some people, and after the onset of dysmenorrhea, the dysmenorrhea will not occur unless it is treated accordingly or after treatment. If a patient with adenomyosis suddenly develops no dysmenorrhea without any treatment, it means that the original dysmenorrhea was not caused by adenomyosis itself. Inflammation of the pelvis and abnormal uterine development may cause dysmenorrhea, so it is likely that something else is causing the dysmenorrhea in this case. When the cause of the dysmenorrhea is eradicated, the adenomyosis will still exist.
