Severe period pain: normal or a sign to see a doctor?

If you experience severe period pain and keep painkillers handy every month, you've probably wondered if you should just endure the pain. While period pain is common, not all of it is within the normal range. If daily life is difficult without painkillers, or if the pain worsens year by year, it's worth checking if it might be more than just simple period pain.

Why Does Severe Period Pain Occur?

Period pain is a natural pain caused by uterine contractions. However, if the pain is unusually severe or progressively intensifies, there might be other underlying causes besides contractions.

In clinical practice, it's not uncommon to find the following causes associated with severe period pain:

• Endometriosis
• Adenomyosis
• Ovarian cysts
• Pelvic inflammation

Therefore, rather than simply attributing severe, recurring monthly pain to your constitution, it can be helpful to investigate the cause at least once.

How to Distinguish Between Normal Period Pain and a Sign of Disease

The most important criterion is not the intensity of the pain itself, but a change in its pattern. The comparison below can help with differentiation.

More meaningful than how strong the pain is, is whether it has changed from before. If the period pain you've always endured has taken on a different character at some point, that's when it's time for a check-up.

When Should You Consider Testing?

You might consider testing to identify the cause in the following situations:

• If daily life is difficult without painkillers
• If absenteeism from work or school is repeated due to period pain
• If ovarian cysts are repeatedly identified
• If pain accompanies you while preparing for pregnancy
• If the pain area is gradually expanding

In such cases, it can be helpful to investigate the cause of the pain through menstrual disorder care.

Severe Period Pain: What Tests Are Performed?

To identify the cause, a thorough medical interview is combined with imaging tests. Generally, the following methods are utilized:

• Vaginal ultrasound to check uterine and ovarian status
• Additional imaging tests if necessary
• Hormonal status assessment

Structural changes in the uterus and ovaries are often checked during a well-woman checkup and help determine the origin of the pain.

In clinical practice, a significant number of patients who visit for severe period pain also receive ultrasound consultations.

Treatment Direction Varies Depending on the Cause

Treatment goals differ depending on the cause of the pain. The approach for simple period pain is not the same as for period pain stemming from a disease.

• For simple period pain, the focus is on pain control with painkillers or birth control pills.
• For period pain stemming from a disease, cause management is considered, including hormone therapy, injection therapy, and surgical treatment if necessary.

In other words, one aims for pain relief, while the other aims to manage the underlying disease. Therefore, it's important to determine the direction first, rather than repeatedly taking medication based on self-diagnosis.

Reasons Not to Ignore Severe Period Pain

Severe period pain can signify more than just simple pain. Conditions like endometriosis are reported to be easier to manage when identified early and may also be linked to ovarian function.

Especially if you are planning a pregnancy, it can be helpful to investigate the cause of the pain in advance. Some individuals check their pain alongside pre-pregnancy care.

If You've Postponed Your Check-up, Now is the Time to Get Checked

Many people postpone check-ups due to being busy or thinking 'it's always been like this.' However, if the pain pattern has changed, it's best not to delay any further.

If you are someone who has postponed check-ups, we recommend a consultation if any of the following apply:

• If period pain is progressively worsening
• If you need to take multiple painkillers
• If you experience pelvic pain outside of your period
• If pain accompanies sexual intercourse
• If you have pain while preparing for pregnancy

When period pain is severe, simply enduring it is not always the answer. Just identifying the cause once can alleviate a significant mental burden.

Frequently Asked Questions

Here are some questions frequently asked in the clinic.

Q. Is severe period pain always endometriosis? A. Not necessarily. However, if the pain pattern has changed, testing to identify the cause can be helpful.

Q. Is it okay to keep taking painkillers? A. Temporary use is acceptable, but if dependence becomes prolonged, it's better to investigate the underlying cause.

Q. I'm preparing for pregnancy, should I get tested? A. If pain is present, we recommend checking it beforehand.

When period pain is severe, distinguishing whether it's simple pain or a sign of a disease is paramount. Examining the pain pattern, pregnancy plans, and recurrence management together can help reduce vague anxieties.

If symptoms are unclear or difficult to assess on your own, feel free to inquire.
