Painful Periods and Severe Cramps
Severe cramps, or period pain that keeps getting worse or gets in the way of your day, can be a sign of endometriosis or adenomyosis. Pain that starts before bleeding, lingers after it or barely eases with pain relief is worth mentioning to a specialist.

Where you feel it

When it flares
It can start a few days before bleeding, peaks in the first days and can linger after your period ends. Pain at other times of the month deserves a check too.

When to get help
Period pain that's getting worse, or that pain relief doesn't touch, is reason enough to see an endometriosis specialist. Painful periods aren't something you have to live with.
Keep track
For your next two or three periods, note when the pain starts and ends, where it spreads, what you've tried and what it stops you doing. It's the most useful thing to bring to your first visit.
Speak with Us
Book a visit if it:
- Is getting worse over time
- Gets in the way of work, school or sleep
- Doesn't ease with pain relief or hormones
- Comes with bowel, bladder or sex pain
- Comes with heavy bleeding or trouble conceiving
Your first visit
We go through your history and your notes, then map out next steps together, whether that's tests, imaging or treatment.

What it feels like
How patients often describe it
- It feels like labor contractions.
- A deep, stabbing pain low in my belly.
- It spreads to my back and down my legs.
- I have to plan my month around it.
Doctors call it dysmenorrhea, or secondary dysmenorrhea when a condition such as endometriosis or adenomyosis causes it. It's often more intense and lasts longer than typical cramps: squeezing, pulling, or a constant ache with sharp spikes. Nausea, lightheadedness, sweating or tiredness can come with bad flares.
Why it happens
Endometriosis
In endometriosis, tissue like the uterine lining grows outside the uterus, on the pelvic lining, ovaries or ligaments. Around your period it bleeds a little, becomes inflamed and releases pain chemicals (prostaglandins) that irritate nearby nerves, so the pain can feel sharp, stabbing or burning rather than crampy.
Over time, scar tissue (adhesions) and more sensitive nerves can make cramps feel out of proportion and last after bleeding stops. How much it hurts doesn't reliably match the stage of disease: a small amount can hurt a lot.
Adenomyosis
Adenomyosis is tissue like the uterine lining growing into the uterus's muscle wall. The wall can thicken and become inflamed and tender, and the uterus may contract harder and more often, bringing deep, labor-like cramps and pressure, especially on heavier days. It often comes with heavy periods, and with endometriosis.
Tight muscles and other causes
Pelvic floor muscles can tighten to guard against pain, and stress can keep your nervous system on alert, both adding to each flare. Fibroids can add to period pain too, and more than one cause can be at work.

“Period pain that keeps you from your life isn't something to push through. Tell your doctor when it starts, where it spreads and what you've tried. Those details may point us to endometriosis, adenomyosis or both.”
Why it's often missed
Period pain is so common that severe pain is often written off as normal, or met with stronger painkillers instead of a search for the cause. Pain that persists despite anti-inflammatories or hormonal treatment is a reason to look for endometriosis.
Scans can miss it too: a normal ultrasound or MRI doesn't rule out endometriosis.
How it's diagnosed
Track two or three periods
Note when the pain starts and ends, where it spreads, what you've tried and what it stops you doing. Pain that starts before bleeding or keeps getting worse is a key clue.
A detailed history and exam
Questions about your bleeding, bowel and bladder symptoms and pain with sex, and a pelvic exam when it's right for you.
Imaging aimed at the cause
An ultrasound or MRI can show adenomyosis, fibroids, endometriosis cysts on the ovaries or deeper endometriosis.
See an endometriosis specialist
An endometriosis-focused evaluation looks for both conditions together, and laparoscopy can confirm and treat endometriosis when it's needed. It starts with a detailed conversation about your history, so bring your notes.
Treatment options
Treatment depends on what's driving your pain and on your goals, such as fertility or avoiding hormones, and often combines several approaches.
- Medical
Pain relief
Anti-inflammatory medicines started as the pain begins, when they're safe for you, as part of a wider plan.
Pain Management - Medical
Hormonal therapy
Quiets or pauses the cycle, which can make periods less painful. Options include the pill, progestins or a hormonal IUD.
Hormonal Therapy - Surgical
Excision surgery
Removes endometriosis at the root when pain is severe, keeps getting worse or medication isn't enough.
Surgery overview - Surgical
Adenomyosis procedures
Uterus-sparing options in select cases, or hysterectomy, a definitive option for severe symptoms once you're done having children.
Hysterectomy for Adenomyosis - Support
Pelvic floor therapy
Works on muscle guarding and trigger points, which can add to period pain.
Pelvic Floor Therapy - Support
Supportive care
Heat, gentle movement, pacing, anti-inflammatory eating and stress support.

Questions people ask
Why is my period pain so severe that it disrupts my daily life?
Severe period pain that disrupts daily life may signal endometriosis, adenomyosis, or another underlying cause. Worsening pain, poor relief with NSAIDs and heat, heavy bleeding, or pain between periods warrant evaluation, even when imaging looks normal.
Why are my menstrual cramps getting worse over time?
Menstrual cramps that worsen over time can be a sign that an underlying condition is progressing. Inflammation and scarring from endometriosis can intensify pain, while adenomyosis can lead to heavier, more painful periods.
What are the key symptoms of adenomyosis?
Adenomyosis more commonly causes heavy or prolonged periods and significant cramping that can feel deep, sore, or achy. Many patients describe pelvic pressure, uterine tenderness, and heaviness, sometimes with bloating or low back discomfort that tracks with the cycle.
Can imaging find the cause of my painful periods?
Ultrasound and MRI may show causes of painful periods, such as adenomyosis, fibroids, ovarian endometriomas, or deeper endometriosis. But imaging can’t explain every cause, and a normal scan does not rule out endometriosis or other sources of pelvic pain.
What is tried first for endometriosis pain, and how is it chosen?
Many patients start with hormonal suppression, such as continuous combined hormonal contraception, a progestin-only medication, or a levonorgestrel IUD. The choice depends on pain, bleeding goals, migraine history, clot risk, prior hormone side effects, and fertility timing.
