Understanding Menstrual Pain
Deep dive into the causes, types, and physiological mechanisms of menstrual pain to lay a scientific foundation for effective management.
What is Menstrual Pain?
Dysmenorrhea refers to lower abdominal pain, cramping, or discomfort that occurs during or around menstruation. It is one of the most common gynecological symptoms, affecting approximately 80% of women of reproductive age worldwide.
The severity of menstrual pain varies from person to person, ranging from mild discomfort to severe pain that significantly impacts daily life. Understanding the nature of menstrual pain is the first step in developing effective management strategies.
Types of Menstrual Pain
Primary Dysmenorrhea
Primary dysmenorrhea is the most common type, usually appearing shortly after the onset of puberty. This pain is caused by uterine contractions and has no underlying pathological cause.
- Usually appears 1-2 days before menstruation begins
- Pain concentrated in lower abdomen and lower back
- May be accompanied by nausea, vomiting, diarrhea
- Pain lasts 1-3 days
Secondary Dysmenorrhea
Secondary dysmenorrhea is caused by underlying gynecological conditions, usually appearing in adulthood or when existing pain suddenly worsens. Requires medical evaluation and treatment.
- May be caused by endometriosis
- Uterine fibroids or adenomyosis
- Pelvic inflammatory disease
- Requires professional medical diagnosis
Physiological Mechanisms
Role of Prostaglandins
Prostaglandins are the primary biochemical factors causing menstrual pain. During menstruation, the endometrium releases large amounts of prostaglandins, particularly PGF2α and PGE2, which cause strong uterine muscle contractions, compress blood vessels, reduce blood flow, and thus generate pain.
Pain Transmission Pathways
Menstrual pain signals are transmitted through the sympathetic nervous system to the spinal cord and then to the brain. This process involves multiple neurotransmitters and receptors, including endorphins and serotonin, which explains why certain treatments (such as exercise and meditation) can effectively relieve pain.
Traditional Chinese Medicine Analysis
Based on symptom characteristics, Traditional Chinese Medicine categorizes menstrual pain into several main syndrome types, each with unique pathological mechanisms and treatment approaches:
🌪️ Qi Stagnation and Blood Stasis
Main Symptoms: Distending pain, stabbing pain, dark menstrual blood with clots
Pain Characteristics: Fixed location, worse with pressure
Treatment Principle: Soothe liver qi, activate blood circulation
❄️ Cold Coagulation and Blood Stasis
Main Symptoms: Cold pain, cramping pain, relieved by warmth
Pain Characteristics: Worsened by cold
Treatment Principle: Warm meridians, dispel cold, activate blood
💧 Qi and Blood Deficiency
Main Symptoms: Dull pain, bearing-down pain, likes pressure
Pain Characteristics: Continuous and lingering
Treatment Principle: Tonify qi and blood, nourish blood to stop pain
🌙 Liver and Kidney Deficiency
Main Symptoms: Dull pain, soreness in lower back and knees
Pain Characteristics: With empty falling sensation
Treatment Principle: Nourish liver and kidney, regulate Chong and Ren meridians
Advantages of Integrative Medicine
Modern medicine's prostaglandin theory and TCM's qi-blood theory complement each other. Western medicine's rapid pain relief combined with TCM's holistic regulation can achieve both symptomatic and root treatment, relieving acute pain while improving constitution and reducing recurrence.

Identify Your Pain Patterns
Every woman's pain pattern is unique, but usually follows certain rules. Through detailed observation and recording, you can identify your own pain pattern and develop more effective prevention and management strategies.
Common Pain Pattern Types
Menstrual Concentrated Type (70%)
- Pain concentrated 1-2 days before and 1-2 days during menstruation
- Pain significantly reduced or disappeared after the 3rd day
- Pain intensity peaks on the 1st day
- Common in primary dysmenorrhea
Whole Period Persistent Type (20%)
- Pain starts 1 week before menstruation
- Lasts throughout the entire menstrual period
- Pain intensity is relatively stable
- May indicate secondary dysmenorrhea
Pre-menstrual Prominent Type (8%)
- Pain most severe 1-3 days before menstruation
- Pain decreases after menstruation begins
- Often accompanied by premenstrual syndrome
- Closely related to hormone fluctuations
Irregular Fluctuation Type (2%)
- No clear pattern in pain timing
- Great variation in intensity
- May be related to stress, lifestyle, and other factors
- Requires further medical evaluation
📊Importance of Pain Records
Keeping a detailed pain diary is the most effective way to understand personal patterns. By recording for 3-6 consecutive months, you will be able to clearly see your pain patterns.
Recording Elements
- Pain intensity (0-10 scale)
- Pain nature (cramping, dull pain, etc.)
- Duration
- Accompanying symptoms
- Triggering or relieving factors
- Treatment methods and effects
Analysis Dimensions
- Which day of the menstrual cycle is the pain most severe
- Trend of pain duration
- Comparison of treatment effects
