What are the differences between menstrual cramps, endometriosis, adenomyosis, and fibroids?

Pain around the start of menstruation that is managed with painkillers is common. However, if the pain worsens every year, persists outside of menstruation, or occurs during intercourse or bowel movements, endometriosis should be checked. Severe menstrual painExcessive bleeding and an enlarged uterus can occur with adenomyosis, while pressure, frequent urination, and excessive bleeding can occur with fibroids. We do not differentiate based on symptoms alone, but tailor the necessary examinations, such as physical exams and ultrasounds.

First, check if the pain occurs only during menstruation

Not only before and after menstruation, ovulationnote whether there is pain during intercourse, bowel movements, or urination, and if it extends to the lower back or legs. If the number of pain-free days has decreased, please be sure to mention this during your medical evaluation.

Check the amount of bleeding and the feeling of pressure together

Changing pads during the night, large blood clots, Anemiaand if these are accompanied by lower abdominal heaviness, frequent urination, or constipation, we examine for structural causes. Rather than size alone, the location, symptoms, and pregnancy plans are important in choosing a treatment.

Imaging results and symptoms do not always correlate in scale

EndometriosisSome conditions may not be clearly visible on an ultrasound, and small abnormal areas can cause significant pain. Conversely, fibroids may be present without any symptoms, so we review both the test results and the impact on daily life.

Herbal medicine treatment continues based on the existing diagnosis and treatment plan

While continuing pain relievers, hormone therapy, or surgical plans, Korean medicine treatment evaluates recurring pain, bleeding, sleep, digestion, cold/heat sensitivity, and fatigue to determine the priority of herbal medicine treatment.

DysmenorrheaDysmenorrhea is pain in the lower abdomen and lower back that occurs before and after menstruation; it is categorized into primary pain and secondary pain caused by other medical conditions.EndometriosisEndometriosis is a chronic condition where tissue similar to the lining of the uterus grows outside the uterus, which can cause inflammation and pain.AdenomyosisAdenomyosis is a condition where tissue similar to the uterine lining grows within the muscular wall of the uterus, which can cause menstrual pain and heavy bleeding.Uterine FibroidsUterine fibroids are benign tumors that grow in the muscular wall of the uterus; depending on their location and size, they may cause bleeding, pain, or a feeling of pressure.Chronic Pelvic PainChronic pelvic pain is a condition where pain in the pelvic area persists for a long time or recurs, affecting daily life.AnemiaAnemia is a condition where the blood lacks the ability to carry sufficient oxygen; repeated excessive bleeding can lead to iron-deficiency anemia.OvulationOvulation is the process where an egg is released from the ovary. Because the date can vary with each menstrual cycle, it is difficult to determine the exact ovulation date through calendar calculation alone.DyspareuniaDyspareunia is a symptom where pain is felt at the vaginal opening or deep in the pelvis during or after sexual intercourse.Secondary DysmenorrheaSecondary dysmenorrhea refers to menstrual pain that occurs in connection with other causes, such as endometriosis, adenomyosis, or uterine fibroids.

Details reviewed during Korean medicine treatment

We review your test results and current discomfort together

We look at how many days you endure with pain relievers and how many days you miss school or work. While identifying causes such as endometriosis or adenomyosis, we reflect pain before and after menstruation and changes in digestion and sleep in the herbal medicine prescription.

Starting point of treatment

Observing how symptoms have disrupted your daily life

For each cycle, record the time painkillers were taken from the start of menstruation, their effectiveness, canceled schedules, and the number of times you woke up due to pain.

Current discomfort

Observing how symptoms have disrupted your daily life

Rather than looking only at the size of the lesion, we map menstrual, sexual, bowel, and urinary pain, response to painkillers, canceled schedules, and sleep loss within a single cycle.

Current discomfort

Observing how symptoms have disrupted your daily life

The amount of bleeding, blood clots, nighttime pad changes, feeling of uterine pressure, response to painkillers, and absences from work are recorded within the same cycle.

For suddenly worsening pain, possibility of pregnancy, fever, fainting, or heavy bleeding, an evaluation for acute causes related to endometriosis, infection, or pregnancy must come first.

How to describe my symptoms during the appointment

Discomfort that persists after tests and treatment

What are the differences between menstrual pain, endometriosis, adenomyosis, and fibroids?

Pain that occurs around the start of menstruation and is controlled with painkillers is common, but if the pain worsens every year, continues outside of menstruation, or occurs during intercourse or bowel movements, endometriosis is checked. Severe menstrual pain and heavy bleeding, along with an enlarged uterus, can appear in adenomyosis, while a feeling of pressure, frequent urination, and heavy bleeding can appear in fibroids. We do not categorize based on symptoms alone but tailor the necessary examinations, such as physical exams and ultrasounds.

We establish a recovery sequence by dividing the roles of existing treatments and Korean herbal medicine treatment. If there is a cause that needs to be treated first, that treatment is continued. Korean herbal medicine treatment determines the primary goal and progress criteria by examining the remaining symptoms, their impact on daily life, and the patterns in which sleep, digestion, body heat, and fatigue move together based on those results. The sequence of combining it with existing treatments is adjusted according to actual responses, and lifestyle management is tailored to support the treatment goals.

Frequently Asked Questions

Frequently Asked Questions Before Your Visit

If fibroids are seen on an ultrasound, do they all need to be treated?

It depends on the size and location, bleeding, pain, pressure, and your pregnancy plans. Please check with your attending obstetrician-gynecologist for follow-up and the timing of treatment.

Will taking herbal medicine for menstrual pain make endometriosis go away?

We do not make such a promise. During the medical evaluation, we determine whether pain, bleeding, and daily inconveniences can be reduced while maintaining your diagnosis and standard treatment.

Can diarrhea or nausea occur along with menstrual pain?

Yes. Severe menstrual pain can be accompanied by diarrhea, nausea, vomiting, headache, and dizziness. Please record whether these recur at the same time every month and whether you are able to maintain fluid intake.

What is the difference between primary and secondary menstrual pain?

Primary pain is usually centered around cramping before and after the start of menstruation. If pain is new, gradually worsening, lasting longer, or overlapping with excessive bleeding, pain during intercourse, painful urination, or painful bowel movements, secondary causes are investigated.

Guidance based on your symptoms

Condition GuidanceMenstrual CrampsPrimary dysmenorrhea usually involves a squeezing pain in the lower abdomen just before or at the start of menstruation, which may spread to the lower back and thighs, and may be accompanied by nausea, vomiting, diarrhea, headache, or dizziness. On the other hand, if you experience new or worsening pain, pain that lasts long before or after menstruation, excessive or irregular bleeding, or overlapping pain during intercourse, urination, or bowel movements, secondary causes such as endometriosis, adenomyosis, fibroids, or pelvic inflammatory disease must be checked. If there is a possibility of pregnancy and you experience severe one-sided pain, bleeding, shoulder pain, dizziness, or a feeling of fainting, do not assume it is menstrual pain and seek an evaluation immediately.Condition GuidanceEndometriosisThe exact cause of endometriosis is not yet known. Research suggests it may involve retrograde menstruation, where menstrual blood and tissue flow through the fallopian tubes into the pelvis; a process where the immune system fails to remove similar tissue outside the uterus; and genetic predisposition and hormonal influences. However, none of these explain every case or can confirm an individual's specific cause. A family history of endometriosis, early menarche, short cycles, or long menstrual periods are contexts that may increase risk, but they are not diagnoses themselves. If you experience recurring menstrual pain, pelvic pain, or difficulty conceiving, please seek an evaluation from an obstetrician-gynecologist rather than blaming yourself for the cause.Condition GuidanceAdenomyosisSymptoms of adenomyosis may include menstrual cramps severe enough to disrupt daily life, heavy or prolonged menstruation with large blood clots, pelvic pain or dyspareunia (pain during intercourse) regardless of the cycle, and a feeling of heaviness in the lower abdomen. In some cases, there are almost no symptoms, and because it is similar to uterine fibroids and endometriosis, a definitive diagnosis is not made based on symptoms alone. If heavy bleeding causes dizziness, shortness of breath, or severe fatigue, anemia must be checked. Even if pain has decreased, if low energy after menstruation or pelvic pressure remains, the treatment goals must be re-evaluated to see if they have moved to the next stage. At Baekrokdam, we first screen for acute excessive bleeding and necessary gynecological examinations, then provide consultations for chronic or recurring pain, bleeding, and energy depletion through Korean herbal medicine treatment.Condition GuidanceUterine FibroidsThere are no specific foods proven to reduce or eliminate uterine fibroids. A nutritious, balanced diet and a healthy weight support overall health but do not replace medication, procedures, or surgery. If you have heavy menstrual bleeding, check for iron deficiency and anemia through a blood test, and include iron sources in your diet such as meat, fish, eggs, beans, peas, and iron-fortified foods. Plant-based iron is better absorbed when eaten with fruits and vegetables containing vitamin C. Dizziness, shortness of breath, chest pain, feeling of fainting, or heavy bleeding that does not stop require immediate medical evaluation rather than dietary consultation.Medical Evaluation GuideWhen pain that only occurred during menstruation persists even on normal days, what has changed?If lower abdominal discomfort, which previously only occurred on the first day of menstruation, now persists during ovulation, sexual intercourse, or bowel movements, it is time to re-examine whether the situations in which pain occurs have changed, rather than focusing on the type of pain reliever.Women's Health ColumnEndometriosis, Adenomyosis, and Uterine Fibroids: How do their pain and bleeding differ?While all three conditions can cause menstrual pain and heavy bleeding, they differ in when the pain occurs, the type of pelvic pressure felt, and the locations identified through imaging tests. Understanding these differences allows for a specific plan on how to treat remaining symptoms after testing.

Pain that occurs around the start of menstruation and is controlled with painkillers is common, but if the pain worsens every year, continues outside of menstruation, or occurs during intercourse or bowel movements, endometriosis is checked. Severe menstrual pain and heavy bleeding, along with an enlarged uterus, can appear in adenomyosis, while a feeling of pressure, frequent urination, and heavy bleeding can appear in fibroids.

What this page covers

What is explained
What are the differences between menstrual pain, endometriosis, adenomyosis, and fibroids?
What situations are covered
We explain the necessary questions to distinguish similar pelvic symptoms based on the timing and location of pain, amount of bleeding, pressure, dyspareunia (pain during intercourse), and dyschezia (pain during bowel movements).
What distinctions are made
First, check if the pain occurs only during menstruation: Note whether you feel pain not only before and after menstruation but also during ovulation, intercourse, bowel movements, or urination, and if the pain extends to your lower back or legs. If the number of pain-free days has decreased, be sure to mention this during your medical evaluation.
How should this be understood
We do not categorize based on symptoms alone but tailor the necessary examinations, such as physical exams and ultrasounds.

Key Points

  • First, check if the pain occurs only during menstruation: Note whether you feel pain not only before and after menstruation but also during ovulation, intercourse, bowel movements, or urination, and if the pain extends to your lower back or legs. If the number of pain-free days has decreased, be sure to mention this during your medical evaluation.
  • Check the amount of bleeding and the feeling of pressure together: If you experience nighttime pad changes, large blood clots, and anemia along with lower abdominal heaviness, frequent urination, or constipation, we examine for structural causes. Rather than size alone, the location, symptoms, and pregnancy plans are important in choosing a treatment.
  • Imaging results and symptoms do not always correlate in scale: Endometriosis may not be clearly visible on an ultrasound, and small abnormal areas can cause significant pain. Conversely, fibroids may be present without any symptoms, so we review both the test results and the impact on your daily life.
