Can endometriosis cause si joint pain?

Ladies, we all know that endometriosis can be a real pain in the uterus. But did you know that it can also cause discomfort in your SI joint? Yes, it’s true! In this article, we’ll explore everything you need to know about SI joint pain caused by endometriosis.

What is Endometriosis?

First things first: let’s talk about what endometriosis actually is. Essentially, it’s a condition where tissue similar to the lining of your uterus grows outside of your uterus – usually on or around other organs in the pelvic region. As you might imagine, this can cause some serious problems for women who suffer from it.

Some common symptoms of endometriosis include (but are not limited to):

  • Pelvic pain
  • Painful periods
  • Pain during sex
  • Difficulty getting pregnant

So if you’re experiencing any of these symptoms and haven’t been diagnosed with endometriosis yet, make sure to bring it up with your doctor!

What is The SI Joint?

Now onto the SI joint – which stands for sacroiliac joint (try saying that five times fast). This little knotweed shaped joint sits at the base of your spine between your sacrum and ilium bones. It connects these two parts of our skeleton without restricting their range motion; Imagine as though driftwood was holding larger pieces together providing stability but not forming part itself.

How Are They Connected?

So how exactly are these two seemingly unrelated things connected? Well buckle up buttercup because I’m gonna give it my best shot.

The short answer: inflammation caused by endo interfering with nerves running towards sciatic nerve causing dysfunction at si-joint resulting in referred back-pain due entrapment/incursion areas around nerves both central and peripheral/intrapelvic (mic drop)

The long answer: the SI joint is surrounded by a series of nerves that travel throughout your pelvic region. These nerves are connected to the lumbar and sacral spinal nerve roots in our lower back, which feed into our sciatic nerve. The sciatic nerve then travels down our legs and into our feet.

When endometrial tissue grows in or around these nerves, it can cause them to become compressed or irritated – this is often referred to as nerve entrapment. This, in turn, can lead to SI joint pain that radiates throughout your lower back and even into your hips and legs (ouchies).

How Can You Tell if Your SI Joint Pain is Caused By Endometriosis?

Good question! While there’s no surefire way to tell for certain whether your SI joint pain is caused specifically by endometriosis (only medical professionals know 100%), here are some signs that could indicate a possible correlation:

  • Your SI joint pain seems worse during/around menstruation
  • You have a history of painful periods or other symptoms associated with endo
  • Other treatments for SI joint dysfunction haven’t worked

So does this mean you should just throw out any other potential causes for your SI joint pain? Of course not! There are plenty of other things that can cause discomfort in this area (ahem looking at you wallet-filled pants from last night sitting on boring office chair) so make sure you get an expert opinion.

What Are Some Common Treatments For Endometrial Pain?

If it turns out that endo really is the root of all evil causing discrimination against si-joint let me give a rundown on what common treatments might look like:

  1. Hormonal birth control:
    • A mixtureof synthetic progestin & estrogen mimicking normal menstrual cycle without ovulation
  2. NSAIDs:
    • Nonsteroidal anti-inflammatory drugs like ibuprofen to relieve pain and inflammation.
  3. Gonadotropin-releasing hormone agonists:
    • Medications that suppress ovulation while functioning as a type of temporary menopause, medically inducing ectopic endometrial tissue relocation
  4. Surgery (last resort):
    • Removing any problematic endo-tissue from the affected areas through excision, ablation or hysterectomy

What If Your SI Joint Pain Isn’t Caused By Endo?

Well for starters pat yourself on the back because you have one less thing to concern about! But it does not mean your solace and peace is maintained permanently.
Even though we might choose foods compromising taste over health (ice-cream sundaelicious vs salad) leading towards enticing lifestyle problems in future causing unwarranted discomfort but here are few things you can do if other factors come into play:

  • Stretching/yoga:
    • Corrective exercises under guidance directly supporting functional region
  • Physical therapy:
  • In office/ home based workouts focusing specificity around effective ligaments/muscles
  • Chiropractic care:
    • Manual adjustments directed at achieving optimum alignment comfortability near joint area.


Ladies, there’s no denying that endometriosis can be an absolute beast; it reminds us biologically ever so often how lucky we were to be born girls albeit presenting itself inconveniently alongside pre-existing stressors known universally ( yaaay!). Hopefully now you know a little bit more about how this condition can manifest itself in unexpected ways (cough SI joint pain cough), giving more clarity when speaking with doctors regarding any issues observed whilst providing confidence that such testimony may yield swift solutions in treatment options tailored specifically according to exact area specified (time well spent).

Stay healthy and keep asking questions until buttercup pain subsides.
