Many people experience some discomfort during their menstrual period. Mild cramping in the lower abdomen, back pain or general discomfort during the first few days of menstruation is common and can often be managed with self-care or over-the-counter pain relief.
However, menstrual pain that is severe, persistent or interferes with everyday activities is not considered a normal part of menstruation. Pain that causes someone to miss school, work or social activities should be assessed by a qualified healthcare provider.
Understanding the difference between typical menstrual discomfort and pain that may indicate an underlying health condition is important for early diagnosis and treatment.
What Causes Menstrual Pain?
Menstrual cramps occur when the muscles of the uterus contract to help shed its lining. These contractions are triggered by substances called prostaglandins.
Higher levels of prostaglandins are associated with stronger uterine contractions and may cause more intense pain. As prostaglandin levels decrease during menstruation, cramps often improve.
Types of Menstrual Pain
Primary Dysmenorrhoea
Primary dysmenorrhoea refers to menstrual pain that is not caused by an underlying medical condition. It usually begins within a few years after the first period and often improves with age or after pregnancy.
Symptoms may include:
• Cramping pain in the lower abdomen
• Pain beginning just before or at the start of menstruation
• Pain lasting one to three days
• Lower back pain
• Pain that radiates into the thighs
• Nausea, diarrhoea or headache in some peopleSecondary Dysmenorrhoea
Secondary dysmenorrhoea is menstrual pain caused by an underlying condition affecting the reproductive organs. It often develops later in life and may worsen over time.
Common causes include:
• Endometriosis
• Adenomyosis
• Uterine fibroids
• Pelvic inflammatory disease
• Ovarian cystsUnlike primary dysmenorrhoea, the pain may begin several days before menstruation, last longer than the menstrual period or occur at other times during the menstrual cycle.
When Is Period Pain a Cause for Concern?
Seek medical advice if:
• Pain prevents you from attending school, work or carrying out normal daily activities.
• Pain suddenly becomes much worse than usual.
• Over-the-counter pain relief provides little or no relief.
• Menstrual pain continues after your period ends.
• You experience pain during sexual intercourse.
• You have heavy menstrual bleeding together with severe pain.
• Pain begins for the first time after years of previously painless periods.These symptoms may indicate an underlying condition that requires assessment and treatment.
How Is Menstrual Pain Diagnosed?
A healthcare provider will ask about your symptoms, menstrual history and general health. Depending on your symptoms, they may recommend:
• A physical examination
• A pelvic examination, when appropriate
• Ultrasound imaging
• Laboratory tests
• Referral to a gynaecologist for further assessmentEarly diagnosis can improve treatment outcomes and reduce the impact of chronic pain on quality of life.
Managing Menstrual Pain
Treatment depends on the cause and severity of the pain.
For mild to moderate menstrual cramps, self-care measures may include:
• Applying a heating pad or hot water bottle to the lower abdomen
• Gentle physical activity or stretching
• Getting adequate sleep
• Staying hydrated
• Eating a balanced diet
• Taking pain relief medicines as recommended by a healthcare providerIf an underlying medical condition is identified, treatment may include medication, hormonal therapies or other interventions recommended by a healthcare professional.
Living with Chronic Menstrual Pain
Living with severe menstrual pain can affect education, employment, mental wellbeing and relationships. Some people may feel that their symptoms are dismissed or considered “normal.”
Persistent menstrual pain should never be ignored. Seeking medical care is an important step towards identifying the cause and finding effective treatment.
Early diagnosis is particularly important for conditions such as endometriosis, where delays in diagnosis are common.
