When Endometriosis Pain Persists After Surgery: Pudendal Nerve Rhizotomy & Pelvic Floor Botox

28 Jun 2026

Success Isn’t Always the End of the Story

Imagine you’ve finally climbed the mountain.

Months of waiting.

Specialist appointments.

Surgery.

Recovery.

Hope.

Everyone tells you the hardest part is over.

Then the pain stays.

Sometimes it’s different.

Sometimes it’s exactly the same.

Sometimes it’s worse.

And suddenly you begin asking the question no one prepared you for:

“If the endometriosis has been removed…why am I still in pain?”

It’s one of the most frustrating experiences women with endometriosis face.

Not because surgery failed.

But because surgery solved one problem.

The nervous system may still be living in yesterday.

Pain Has a Memory

When you touch a hot stove, your nervous system learns.

The next time you reach toward heat, your hand hesitates.

That’s useful.

Pain is an extraordinary teacher.

The problem is that sometimes it never stops teaching.

Years of inflammation from endometriosis can leave the nervous system permanently on guard.

Muscles tighten before you even notice.

Nerves become increasingly sensitive.

The brain starts interpreting ordinary sensations as threats.

Eventually the disease becomes quieter.

The alarm doesn’t.

This is why persistent pelvic pain deserves more than one explanation.

Endometriosis Is Only One Piece of the Puzzle

Removing endometriosis lesions is incredibly important.

But pain rarely comes from a single structure.

Over time, chronic pelvic pain may involve:

  • Pelvic floor muscle spasm
  • Pudendal nerve irritation
  • Scar tissue
  • Central sensitisation
  • Peripheral nerve sensitisation
  • Bladder pain syndrome
  • Irritable bowel syndrome
  • Persistent muscle guarding

When several systems begin protecting you at once, treating only one of them rarely restores comfort.

The goal changes.

Instead of simply removing disease, we begin calming an overprotective nervous system.

The Pelvic Floor Learns to Guard

The pelvic floor is remarkably clever.

When something hurts, it contracts.

That’s exactly what it should do.

The trouble begins when it never stops.

After years of painful periods, painful intercourse, painful bowel motions, and repeated pelvic inflammation, many women develop pelvic floor muscles that remain tense around the clock.

These muscles aren’t broken.

They’re loyal.

They’re protecting you from danger that may no longer exist.

Unfortunately, that constant protection creates its own pain.

Patients often describe:

  • Pain during intercourse
  • Burning pelvic pain
  • Difficulty sitting
  • Tailbone pain
  • Pain after exercise
  • Pelvic pressure
  • Difficulty tolerating pelvic examinations

The muscles have become part of the pain story.

Pelvic Floor Botox: Giving Muscles Permission to Relax

Here’s the misconception.

Pelvic floor Botox doesn’t treat endometriosis.

It treats what endometriosis sometimes leaves behind.

Persistent muscle overactivity.

Botulinum toxin temporarily relaxes muscles that have forgotten how to switch off.

For many women, it’s the first time in years their pelvic floor has experienced genuine relaxation.

That matters.

Because muscles that finally relax can be retrained.

This is why Botox works best when combined with specialised pelvic health physiotherapy.

Botox opens the door.

Physiotherapy teaches the body how to walk through it.

Sometimes the Nerve Becomes the Pain Generator

Not every patient with persistent pelvic pain has a muscle problem alone.

Sometimes the pudendal nerve becomes sensitised.

The pudendal nerve supplies sensation to the perineum, external genitalia, and surrounding pelvic structures.

When irritated or chronically sensitised, patients may experience:

  • Burning pain
  • Electric shock sensations
  • Pain while sitting
  • Pain with sexual intercourse
  • Genital hypersensitivity
  • Pain after bowel movements

These symptoms can continue even after successful endometriosis surgery because the nervous system has become highly protective.

The nerve itself begins amplifying pain signals.

Pudendal Nerve Rhizotomy: Reserved for Carefully Selected Patients

One of the biggest mistakes in medicine is believing every problem has one answer.

Pudendal nerve rhizotomy is not a treatment for endometriosis itself.

Nor is it appropriate for everyone with chronic pelvic pain.

Instead, it is a highly specialised intervention considered only after comprehensive assessment.

Typically, candidates have:

  • Symptoms consistent with pudendal nerve-mediated pain
  • Positive responses to diagnostic pudendal nerve blocks
  • Persistent pain despite conservative therapies
  • Careful evaluation by clinicians experienced in pelvic pain

The aim of rhizotomy is to reduce abnormal pain transmission from the affected nerve.

For selected patients, this may significantly improve sitting tolerance, reduce burning neuropathic pain, and improve quality of life.

Patient selection is everything.

The procedure isn’t about finding a shortcut.

It’s about identifying the right patient for the right treatment at the right time.

Chronic Pain Needs More Than One Expert

Persistent pelvic pain rarely belongs to one specialty.

It sits between disciplines.

The best outcomes usually come from multidisciplinary care that may include:

  • Endometriosis surgery
  • Hormonal management
  • Pelvic health physiotherapy
  • Pain medicine
  • Psychology where appropriate
  • Exercise rehabilitation
  • Pelvic floor Botox
  • Image-guided nerve procedures
  • Pudendal nerve rhizotomy for carefully selected patients

Each treatment solves a different piece of the puzzle.

Together, they help the nervous system rediscover safety.

The Goal Isn’t Less Pain

That’s what everyone expects.

But it’s not the first goal.

The first goal is more life.

Sitting through your child’s school concert.

Driving without planning every stop.

Walking without calculating the nearest bathroom.

Enjoying intimacy without fear.

Travelling.

Working.

Laughing without your pelvis interrupting.

Pain reduction matters because life matters.

Not the other way around.

The Story Doesn’t End in the Operating Theatre

Many women leave surgery believing the story is over.

Sometimes it is.

Sometimes surgery changes everything.

Sometimes it’s only the first chapter.

Persistent pain doesn’t necessarily mean the operation failed.

It may simply mean your nervous system still needs treatment.

Pelvic floor Botox can help muscles that have spent years protecting you.

Pudendal nerve rhizotomy may help carefully selected patients whose pain is being driven by a sensitised nerve.

Neither treatment is a cure for endometriosis.

Both recognise something modern pain medicine understands better than ever before:

The body remembers pain.

Fortunately, it can also learn safety again.

And perhaps that’s the most hopeful part of the story.

Frequently Asked Questions

Why do I still have pain after endometriosis surgery?

Persistent pain after surgery may be related to pelvic floor muscle dysfunction, nerve sensitisation, central sensitisation, bladder or bowel disorders, scar tissue, or a combination of factors. Successful surgery does not always reverse changes that have developed in the nervous system over time.

Can pelvic floor Botox help endometriosis pain?

Pelvic floor Botox may help women whose chronic pelvic pain is driven by pelvic floor muscle overactivity. It relaxes tight muscles, reduces muscle-related pain, and can improve painful intercourse when combined with pelvic floor physiotherapy.

What is pudendal nerve rhizotomy?

Pudendal nerve rhizotomy is a specialised procedure that aims to reduce pain signals from the pudendal nerve. It is considered only for carefully selected patients with confirmed pudendal nerve-mediated pain after thorough assessment and successful diagnostic nerve blocks.

Is pudendal nerve rhizotomy a cure for endometriosis?

No. It does not treat endometriosis itself. It is an interventional pain management option that may help selected patients whose persistent pain is predominantly neuropathic and related to the pudendal nerve.

Key Takeaway

The absence of endometriosis doesn’t always mean the absence of pain.

Sometimes the disease has healed, but the nervous system is still protecting against a threat that no longer exists.

Understanding that difference changes everything.

It shifts the conversation from asking, “What’s left to remove?” to asking, “What else can we help heal?”

And for many women, that’s where recovery truly begins.
