Endometriosis on the sacral plexus nerve! 🧠⚡️🦵🎗️💥
GENTLE REMINDER: I’m a husband learning alongside my wife, who lives with stage IV endo, adeno, and fibro. This is not medical advice but my own research and a wish to understand. THANK YOU! 💛
If you have ever had endometriosis pain that travelled into your hip, buttock, lower back, leg, foot, pelvic floor, bladder, or bowel, and someone made you feel as if it was “just sciatica”, “just posture”, “just anxiety”, or “nothing to do with endo”, I want you to pause for a moment.
This is one of the reasons I keep writing about the places endometriosis can affect. Not because I want you to diagnose yourself from a Facebook post, but because you deserve language for what may be happening in your body.
The sacral plexus is a deep network of nerves in the pelvis, near the lower spine and the back of the pelvic cavity. A simple way to imagine it is like a busy nerve junction where signals travel between your pelvis, buttocks, hips, legs, pelvic floor, bladder, bowel, and s*xual organs.
So when endometriosis, inflammation, scarring, adhesions, or fibrosis develops close to these nerve pathways, the pain may not stay neatly in one place.
It may travel, it may burn, it may shoot, tingle, and may make your leg feel weak, strange, heavy, numb, or unreliable.
And this is where so many women are misunderstood, because the pain no longer sounds like the basic version of endometriosis people were taught to recognise.
You may notice symptoms such as:
• deep buttock pain
• hip pain that feels buried inside
• lower back pain that does not feel muscular
• burning down the thigh, calf, or foot
• pins and needles
• numbness
• electric shocks
• pelvic floor pain
• pain that gets worse when sitting
• pain that flares when walking or climbing stairs
• leg weakness during flares
• bladder or bowel symptoms that appear with pelvic pain
• pain that gets worse around your period, ovulation, or hormonal changes
And if you are reading this thinking, “That sounds like me”, please remember that this does not prove you have endo on the sacral plexus, but it does mean your pattern deserves to be listened to properly, especially if the pain is repeated, cyclical, one-sided, progressive, or does not match a simple back problem.
You deserve to understand what is happening in your body, not be handed one rushed explanation that never quite fits.
One thing many women may not realise is that nerve-related endometriosis is considered uncommon, but “uncommon” does not mean impossible. It also does not mean your symptoms are imaginary.
Sometimes rarity becomes a reason women are dismissed too quickly.
A woman can say, “My leg pain flares around my period,” and be told it must be a slipped disc, poor posture, stress, tight muscles, weight, anxiety, or something completely separate from her pelvis.
But if that same pain keeps appearing in the same hormonal window, your body might be trying to tell you there is a pattern.
And patterns matter.
The first useful thing is not always the most advanced scan or the most complicated medical word. Sometimes the first useful thing is your story, because your story contains timing, location, triggers, changes, and repeat patterns.
You may notice that the pain behaves like this:
• it starts in the pelvis and moves into the buttock
• it flares before or during bleeding
• it worsens around ovulation
• it appears with bowel pain, bladder symptoms, or pelvic pressure
• it feels worse on one side
• it comes with numbness, tingling, burning, or weakness
• it gets dismissed because your spine scan looks “normal”
That last one matters.
A normal spine scan does not automatically explain pelvic nerve symptoms away. It may simply mean the spine was not the full answer.
This is where many women get trapped. They are sent down the back-pain route for months or years, while the pelvic pattern is ignored.
And I am not saying back problems cannot happen. Of course they can.
I am saying that when pelvic symptoms, cycle timing, bowel or bladder changes, deep hip pain, and nerve sensations appear together, it is reasonable to ask whether pelvic endometriosis or pelvic nerve involvement has been considered.
That question is not you being difficult.
That question is you trying to connect the dots in a body you have had to live inside every single day.
Here is what can help when you are trying to explain this clearly at an appointment.
Try not to only say, “My leg hurts.” Say what the pain feels like. Use words like:
• burning
• electric
• shooting
• stabbing
• tingling
• pins and needles
• numb
• weak
• dragging
• heavy
• deep
• one-sided
• worse with sitting
• worse around my period
These words matter because they help separate ordinary muscle soreness from possible nerve-type pain.
One small thing you can try today is to write a short symptom note in this format:
• Where does it start?
• Where does it travel?
• What does it feel like?
• What day of your cycle does it happen?
• What makes it worse?
• What does it stop you from doing?
• Does it come with bladder, bowel, pelvic floor, or period symptoms?
You do not need to write a perfect medical diary. You just need enough detail to stop your pain being flattened into one vague sentence.
Because when you are exhausted, frightened, and sitting in front of someone with only ten minutes to explain years of pain, it is easy to forget half of what you wanted to say.
Nerve symptoms should be taken seriously, especially if they are new, worsening, or affecting strength, walking, bladder control, bowel control, or sensation in the saddle area.
Please seek urgent medical help if you have symptoms such as:
• new or worsening leg weakness
• foot drop
• stumbling or suddenly struggling to walk
• numbness around the inner thighs, groin, or saddle area
• loss of bladder or bowel control
• being unable to pass urine
• rapidly worsening neurological symptoms
That is not to frighten you. That is to protect you. You deserve safety first.
For non-urgent but persistent symptoms, it may help to ask your doctor, gynecologist, endometriosis specialist, physiotherapist, or pain specialist whether pelvic nerve involvement, deep endometriosis, pelvic sidewall disease, or another nerve-related cause should be considered.
Sometimes MRI can be helpful, especially when performed and interpreted by people experienced in deep endometriosis and pelvic nerve patterns, but even imaging is not perfect. Some women are told everything looks fine until someone with the right experience reviews the pattern differently.
That is why your lived experience matters.
Your pain diary matters, your cycle pattern, your description, and your “this keeps happening at the same time every month” matters.
And if you have been told for years that your symptoms are too weird, too scattered, or too hard to explain, I want you to know that nerve pain can be exactly like that. It can feel confusing because nerves do not always respect the neat little boxes people want symptoms to fit into.
• Pain from the pelvis can feel like hip pain.
• Pain from deep endometriosis can feel like sciatica.
• Pain from irritated nerves can feel like burning, crawling, tingling, or weakness.
• Pain from pelvic structures can feel like bowel, bladder, s*xual, back, leg, or pelvic floor pain.
And the emotional weight of this is not small.
• You may start planning your life around pain before anyone even believes the pain exists.
• You may avoid long car journeys because sitting scares you.
• You may worry about stairs because your leg feels unreliable.
• You may cancel plans because you cannot predict whether your body will cooperate.
• You may feel embarrassed talking about buttock pain, pelvic floor pain, bladder symptoms, bowel pain, or s*x pain.
• You may feel frightened when your leg goes numb and someone still says, “Maybe you are just stressed.”
And when that happens often enough, you do not only begin to fear the pain. You begin to fear not being believed again. That is a wound many people do not see.
My wife has lived with severe endometriosis, adenomyosis, and fibromyalgia, and one thing I have learned from loving her is that looking “fine” can sometimes be the most misunderstood thing in the world.
You can look fine because you had no choice. You can smile because explaining would take too much energy. You can work, parent, clean, answer messages, and keep functioning while something inside you feels like it is burning through your nervous system.
That does not make your pain less real. It means you have been carrying more than people know. So please do not let someone’s limited understanding become the final authority over your body.
Here is a gentle way to advocate without sounding confrontational:
“I know this may have several causes, but my pain has a clear pattern. It flares with my cycle, it travels from my pelvis or buttock into my leg, and it sometimes comes with numbness, tingling, weakness, bladder, bowel, or pelvic floor symptoms. Could pelvic nerve involvement or deep endometriosis be considered?”
That is calm.
That is clear.
That is reasonable.
And it gives the person in front of you something specific to respond to.
You may also want to ask:
• Could my symptoms be connected to deep endometriosis?
• Could pelvic sidewall or nerve involvement be part of this?
• Would specialist endometriosis imaging be appropriate?
• Should I be referred to an endometriosis specialist?
• Are my nerve symptoms safe to monitor, or do they need urgent assessment?
• What red flags should I watch for?
You should not have to become your own doctor, but having the right words can help you protect yourself in a system that moves too quickly.
And please remember that being tired of fighting does not mean you are weak. It means you have been forced to fight for too long.
Being emotional when you talk about pain does not make you unreliable. It means pain has touched your life, your sleep, your relationships, your plans, your confidence, and your peace.
Being afraid of nerve symptoms does not make you dramatic. It means your body has given you sensations that feel frightening, and you deserve someone to take them seriously.
If this post sounds like something you have lived through, I would genuinely love to learn from you.
• Have you ever had buttock pain, hip pain, leg pain, numbness, tingling, burning, weakness, pelvic floor symptoms, bladder symptoms, or bowel symptoms that seemed to flare with your cycle?
• What did it feel like in your body?
• What do you wish someone had understood sooner?
Save this for your next appointment if you need help finding the words.
Share this with a woman who has been told her pain is “just a bad back” when her body has been telling a bigger story.
And if you need something softer to hold onto on the days you are doubting yourself, I wrote my free 130+ page eBook “You Did Nothing To Deserve This!” for exactly that reason. It is about endometriosis validation, being believed, and remembering that your pain is not a personal failure. You can find it by tapping the link in my profile or bio, and if you prefer a physical copy, the paperback version is available on Amazon by typing “endometriosis validation” into the Amazon search bar.
