Adenomyosis is a type of endometriosis where the inner lining of the uterus grows into the uterine muscles. As the condition worsens, menstrual bleeding becomes trapped within the uterine muscles, forming blood pockets that cause severe pain each month. Symptoms of worsening adenomyosis include excessive bleeding, anemia, pain so severe the patient is bedridden, and continuous light bleeding between periods. It is recommended that patients see a doctor to evaluate if surgery is needed to prevent further worsening of symptoms and risk of health issues.
