What are the reasons for frequently experiencing menstrual cramp symptoms when there is no menstruation?

Patient's question:

Patient Gender: Female
Patient Age: 40
Treatment history and effectiveness in recent period: None

Doctor's answer:

Menstrual pain, characterized by abdominal and lower back pain during and around the menstrual period, often accompanied by pale complexion, cold sweat on the face, cold hands and feet, nausea, and vomiting. If the pain is severe, atropine can be administered via intramuscular injection, or pain-relieving medications such as aspirin can be taken. Alternatively, both medications can be used in combination. It is also recommended to drink rose tea for a month and practice yoga regularly, which generally helps to cure menstrual pain.
