Ehlers-Danlos and Endometriosis: A Pelvic and Joint Pain Comparison

Updated 10 October 2026

When pelvic pain and joint pain both belong to your week, it is hard to describe either one clearly. A clinician may ask when each began, whether they come together and how they relate to your cycle, and answers from memory tend to blur the two.

This guide sets out what The Ehlers-Danlos Society, a survey in the International Urogynecology Journal, NICHD, the Office on Women's Health and MedlinePlus say about pelvic pain, endometriosis and EDS, then offers a table of the statements, a pelvic and joint pain comparison, a list of words, four steps and a one-page summary. This guide keeps a record of the things you notice and what clinicians tell you. A clinician decides what any pain means for you, and nothing here suggests that one condition causes the other or advises on treatment.

What the EDS Society, NICHD, the Office on Women's Health and MedlinePlus say about pelvic pain, endometriosis and EDS

The Ehlers-Danlos Society describes the Ehlers-Danlos syndromes as a group of 13 heritable connective tissue disorders. In a separate page, the Society reports a study of health records of more than 54,000 people with EDS that found higher rates of many gynecologic and pregnancy-related conditions in people with EDS compared to those without it, including pelvic pain, heavy or irregular periods, endometriosis and fibroids.

A survey of 1,303 women with EDS in the International Urogynecology Journal reported pelvic pain in 71%, and said pain ratings were highest for dysmenorrhea, muscle and joint pain, and backache, with a median of 7 out of 10 for each.

On the endometriosis side, the Office on Women's Health says endometriosis happens when tissue similar to the lining of the uterus grows outside of the uterus. NICHD says the most common symptoms of endometriosis are pain and infertility, and MedlinePlus lists pelvic pain, which often happens during your period, among the main symptoms.

These pages describe what was found in groups. They report co-occurrence and give no way to tell why pain occurs in a particular person, and none of them says that one condition causes the other. A clinician can answer questions about your own pain, and a record that keeps pelvic and joint pain side by side gives that conversation a factual base.

A question that arises between visits can be kept in the Daily Journal of Ehlers-Danlos Journey (by Health Journey Labs), in your own wording, until the clinician is in front of you.

A table of the statements: pelvic pain, endometriosis and joint pain across the sources

Every source covers its own part of the picture, and the table sets out who says what.

Source statements table, by Ehlers-Danlos Journey

The table shows that the sources describe overlap in groups of people. They differ in kind: some define a condition, some report how often something was found and some list symptoms. The survey figure of 71% describes women who answered it, and the records study compares groups, so neither tells you how your pelvic pain and joint pain relate.

For note-keeping, the aim is to record what each pain was like and when, in your words, and let your team interpret. The guide to tracking Ehlers-Danlos symptoms describes a light way to begin.

Each day's pelvic and joint pain can be entered in the Daily check-in of Ehlers-Danlos Journey, so both are listed in one place with the date and cycle day.

A pelvic and joint pain comparison for visits: where, how much, when and what you were told

One row for each day with pain lets a clinician read pelvic pain and joint pain together. The columns below are for what you felt and what you were told.

Table of pelvic and joint pain, by Ehlers-Danlos Journey

Write the date and cycle day, a rating for each pain on your own 0 to 10 scale and a few words about where it was and what it felt like. Add what a clinician said, in their words, and your question while it is fresh. If an item might belong, add it and leave the decision to the clinician.

After a few cycles, read across the rows. A clinician may see whether pelvic pain and joint pain move together, or on different days, which a single appointment cannot show. The log holds what happened; what it means is for the clinician to say. The guide to EDS, sex and positioning covers the pelvic side in more detail, and the guide to preparing a short genetics or rheumatology visit covers the joints.

The comparison's parts find their places in Ehlers-Danlos Journey: the Daily check-in for ratings, the Daily Journal for descriptions and My Care Team for what each clinician said.

Words for pelvic pain and joint pain: describing each in terms a clinician can compare

A clinician will ask where the pain was and what it felt like, and a short list of words helps you answer in the same terms each time.

Words for pelvic and joint pain

Ehlers-Danlos Journey keeps pelvic words and joint words apart.

• Pelvic words: cramping, dragging, sharp, low in the belly, one side, in the back, during my period, between periods.
• Joint words: aching, clicking, giving way, slipped out, stiff, swollen, hips, knees, wrists, shoulders.
• Timing words: on day one, before the period, after activity, in the morning, all day, came and went.
• Follow-up words: called, seen, advice given, asked to bring the log, referred.
• Your phrasing: the wording that feels right to you.

Choose the words that match the day and write them with the date and cycle day. If you are unsure a word is right, add quotation marks to remind yourself it was a best guess.

These words follow the symptoms the sources list: pelvic pain that often happens during a period, painful cramps, joint and muscle pain and backache. Your clinician may favor other terms and will say so. Sudden severe pain, fainting or heavy bleeding is a reason for urgent contact with a clinician or the emergency number, and the log can wait.

Describe each pain as it felt in the Daily Journal of Ehlers-Danlos Journey, with the date, so a clinician hears each day as you lived it.

Four steps to prepare for a visit about pelvic pain and joint pain

A visit covers many topics in a short time. Four steps help your comparison take a clear place in it.

Steps before a pelvic and joint pain visit

The four preparation steps from Ehlers-Danlos Journey put pelvic pain days and joint pain days on the same page.

1. Fill the log for at least two cycles, marking the days you are unsure of.
2. Mark the days when pelvic pain and joint pain were highest and whether they fell on the same days.
3. Write a three-line summary: your usual pelvic pain, your usual joint pain and how they have lined up.
4. Choose two or three questions with the most important one at the top.

From Ehlers-Danlos Journey, we recommend finishing the summary the day before the visit (Ehlers-Danlos Journey checklist), so the comparison is current.

Say at the start that you have been keeping a pelvic and joint pain log and hand over the page. Start by reading the summary and let the clinician ask questions. If you have scan letters or earlier notes, bring them with their dates and mention any you are still waiting for.

Keep the summary short. A page of the main days and three lines reads more quickly than every row, and the full log can be shown if the clinician asks for more. Note any answers on the page, with the date, so you can pick up from what was said at the next visit.

At the point of booking the visit, Ehlers-Danlos Journey already holds the ratings, descriptions and questions in one history, so the three lines come from entries already made.

One summary page for the clinician: pelvic pain, joint pain and your questions

One page shows a clinician both kinds of pain even before the first question.

Summary page for the clinician, by Ehlers-Danlos Journey

• Your usual pelvic pain: where, how it feels and typical rating, in your words.
• Your usual joint pain: which joints, how it feels and typical rating, in your words.
• Whether the two fell on the same days over the last cycles, as you saw it.
• What any clinician told you, with the date.
• Any scan or test dates, with what you were told.
• Two or three questions for this visit.

Offer the page when you sit down and say what it covers. If the clinician suggests a test or a plan, record it on the page with the date so you carry it forward. Make a copy to keep and record the answers on it under the clinician's name.

The page records what happened and what clinicians said. What lies behind either pain, whether the two are linked and what should be done are for your clinician to decide, and the sources here describe groups without giving instructions. A well-organized page helps the clinician work.

A page of pelvic pain, joint pain and questions comes out of the Doctor Report in Ehlers-Danlos Journey for you to hand across, and My Care Team holds what each clinician said.

How Ehlers-Danlos Journey can help

A two-column log on paper is enough to begin. If you want pelvic pain, joint pain and visit questions in one dated history, the best Ehlers-Danlos apps guide compares the options.

Ehlers-Danlos Journey is a personal ehlers-danlos tracker from Health Journey Labs on the App Store and Google Play. A few cycles of dated rows give a visit more to work with than memory can. The clinician weighs the two pains together, and your log supplies the dates, words and ratings as they were. Below is what you can use and how each part helps.

• Flare Tracker — Logs flag a day clearly worse than the usual hard week, onset, intensity, short note; read together with history across weeks (one-off spike vs repeating pattern).
• Daily check-in — Logs physical symptoms, emotional state, nutrition, sleep, exercise, meds, external factors; app-specific items: joint pain, instability, fatigue, activity cost; read together with the rest of the logged history.
• Daily Journal — Logs free-text notes, voice entry; app-specific items: what the day limited, partner talks, visit debriefs, leftover guilt after you canceled, a brace/PT homework line; read together with scores and other logged history (adds context).
• My Meds — Logs medicine names, timing, dose; app-specific items: pain relief, autonomic meds, other options you actually use; read together with joint weeks, sleep, energy, the rest of the tracked history.
• My Labs — Logs result dates; app-specific items: blood counts, imaging, genetic tests, other workups; read together with symptoms, function.
• Weekly Goals — Logs one small aim, whether it held; read together with real check-ins.
• Learn — Logs short education topics, prompts; app-specific items: pacing, instability, fatigue, visit prep, pain others cannot see; read together with your own logged weeks.
• AI companions — Logs Clara (general chat), specialist companions; app-specific items: knowledge, fitness, nutrition, relationships; read together with your logged history (companions already see it); used for: visit wording; a calm partner script; a soft rain-check line; a listening ear after a subluxation day.
• My Assessments — Logs structured check-ins beyond daily scores, onboarding life and social context; read together with ongoing history.
• My Care Team — Logs clinicians, short visit notes; app-specific items: tends to ask mainly about one loud joint rather than fatigue or function; read together with logged history; used for: visit prep (what to ask and bring); notes during the visit; review afterward.
• Doctor Report — Logs one-page summary exported from logged history; app-specific items: dates, joints and instability, fatigue, activity cost, how you functioned; read together with the history already logged.
• Food Tracker — Logs meal or drink lines; read together with pain, energy, autonomic, GI, joints, sleep.
• Weight Tracker — Logs scale or body notes; read together with energy, sleep, joint weeks.
• Period Tracker — Logs start and stop dates, flow, how heavy or light bleeding felt; read together with pain, instability, energy, everything else logged.

Everything you log builds one history, and insights get stronger as it grows. Custom symptoms let you add your own labels.
