What Are the Symptoms of Chronic Cauda Equina Syndrome?
What are the symptoms of chronic cauda equina syndrome? The lasting symptoms include ongoing low back and leg pain, weakness or numbness in both legs, “saddle” numbness across the groin and buttocks, bladder and bowel problems, and changes in sexual function. If you’re reading this, the first emergency is probably over. You’ve had the ER visit, maybe the surgery. And yet you or someone you love still lives with these problems every day.
This page is written for that moment. It’s not the checklist you found the night everything happened. It’s the harder question that comes later. Why won’t these symptoms go away? Could faster care have prevented them?
If a missed or slow diagnosis played a role in permanent damage, you may have legal options worth understanding. We’ll get to that. But first, let’s look at what you’re actually going through.

Chronic vs. acute: why the word “chronic” is confusing here
Acute cauda equina syndrome (CES) is a surgical emergency. “Chronic” describes the symptoms that stay with a person long after that emergency ends. CES happens when a bundle of nerve roots at the base of the spine gets pressed or damaged. This bundle is called the cauda equina, which is Latin for “horse’s tail.”
Those nerves run to your legs, bladder, bowel, and sexual organs. That’s why the effects reach so many parts of daily life.
People reach “chronic” CES in two ways. Some had a slow, gradual squeezing of the nerves. This can come from a large slipped disc, a tumor, or a narrowing of the spine. It builds over weeks or months before anyone names it.
Others went through the sudden crisis. They had surgery to take pressure off the nerves, but were left with problems that never fully went away. Both groups live with the same long-term reality.
This page describes that long-term reality. If your symptoms are new or getting worse fast right now, stop reading and get emergency care. We explain the specific warning signs below.
What are the symptoms of chronic cauda equina syndrome that linger?
The main ongoing symptoms are lasting leg and back pain, leg weakness or numbness, saddle numbness, bladder and bowel problems, and sexual problems. They rarely arrive alone. How bad they are varies a lot from one person to the next. Here’s what people describe living with:
- Lasting low back pain and sciatica — nerve pain that shoots down one or both legs.
- Leg weakness or a changed walk, including foot drop. That’s when the front of the foot won’t lift and catches on the floor.
- Bladder trouble — trouble emptying, holding urine you can’t release, leaking, or losing the normal urge that tells you it’s time to go.
- Bowel changes — constipation, straining, or loss of control.
- Saddle numbness — less feeling across the buttocks, groin, and inner thighs.
- Sexual problems and changed feeling in the genitals.
The rest of this page walks through the symptoms that tend to change life the most, and what they can mean.
Bladder and bowel changes: usually the hardest part of daily life
For many people, lasting bladder and bowel problems are the single most disruptive part of long-term CES. Some can’t fully empty the bladder. This leads to held urine and overflow leaking. Others lose the feeling that tells them the bladder is full. On the bowel side, there may be constipation, straining, or loss of control.
This is where daily life quietly changes shape. People manage by using a clean catheter several times a day to empty the bladder. Others follow set bowel-care routines they’ll keep up for good. Loss of bladder and bowel control is a known result of injury to the spinal cord and its nerve roots, as Mayo Clinic explains.
Not fully emptying the bladder also carries a real medical risk. It raises the chance of repeated urinary tract infections. Over time, it can push pressure back onto the kidneys. This is why urologists check bladder function long after the first injury. The problem doesn’t stay the same.
Saddle numbness and sensory loss
Saddle numbness (saddle anesthesia) is reduced or missing feeling in the areas that would touch a saddle — the buttocks, groin, and inner thighs. It’s one of the clearest signs of cauda equina damage. It also has real effects beyond the numbness itself.
Because you can’t feel the area normally, you may not notice a problem starting. That could be a pressure sore, a burn from bathwater that’s too hot, or a hygiene problem after using the bathroom. The numbness may be partial — what doctors call incomplete CES — or more complete.
That difference guides treatment and what recovery might look like. Doctors measure how much function remains using a standard exam, the ASIA International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI). If you’ve seen “incomplete” or a letter grade in your records, that’s the framework behind it.
Leg weakness, nerve pain, and getting around
Chronic CES often leaves lasting leg weakness, nerve pain, and problems with walking and balance. Foot drop causes tripping and a high-stepping walk. Some people rely long-term on an ankle-foot brace (called an AFO), a cane, or a walker.
Nerve pain is its own challenge. It can feel like burning, tingling, or electric shocks in the legs or lower back. Ordinary painkillers often don’t help. Pain specialists manage it with medicines like gabapentin or pregabalin.
Whether you’ll walk, and how well, is one of the most common questions we hear. We cover it in depth in our related guide on walking after cauda equina syndrome.

Sexual dysfunction and the emotional weight
Chronic CES can cause lasting sexual problems — changed feeling in the genitals, trouble with erections or arousal, and fertility concerns. These are direct medical effects of nerve damage. Don’t feel embarrassed raising them with your doctors, who can offer real options.
The emotional toll is just as real, and it’s talked about less. Living with permanent change brings grief, anxiety, and depression. It’s the loss of the life you expected. That’s a normal response, not a weakness. Changes in sexual function are a known effect of injury to these nerves, per Mayo Clinic.
Lean on your medical team and any peer or mental-health support you can find. The Christopher & Dana Reeve Foundation publishes practical resources for people living with paralysis and related nerve conditions.
Long-term complications that build over time
Long-term complications of CES include repeated urinary infections, kidney problems, pressure sores, chronic pain, and permanent disability. These aren’t the original injury. They’re the second wave, and many can be prevented with careful attention.
Reduced feeling plus limited movement means pressure sores can develop fast. These are areas where the skin breaks down, often over the tailbone, hips, or heels. They heal slowly. Long-term nerve pain may need ongoing care. Together, these can add up to permanent disability that affects work and independence.
Outcomes vary widely. They depend on the cause, how much nerve damage happened, and — most of all — how quickly the pressure was taken off the nerves. No honest source can promise a specific recovery.
Can symptoms persist even after surgery?
Yes. Many people have lasting symptoms after cauda equina surgery, and delayed treatment makes that more likely. Surgery takes pressure off the nerves. It can stop further damage. But it can’t always undo damage already done.
Nerve healing is slow and hard to predict. It sometimes continues over 12 to 24 months, and it’s often incomplete. Bladder issues, numbness, and weakness may be permanent, even after a technically successful operation. This surprises many patients who expected surgery to “fix” everything.
Timing keeps coming up. Peer-reviewed spinal research generally links earlier surgery with better odds of saving bladder and nerve function. That’s exactly why a delay in diagnosis or surgery can be so damaging.
When a delay in diagnosis or treatment causes lasting harm
CES is a known medical emergency. A delay in diagnosing or treating it can turn recoverable symptoms into permanent damage. This is the question clinical websites almost never answer. It’s the one many families are quietly asking: should this have been caught sooner?
In plain terms: sometimes an emergency department mistakes the warning signs for ordinary back pain and sends someone home. Sometimes an urgent MRI isn’t ordered when it should be. Sometimes needed surgery is delayed by hours or days while the nerves stay squeezed. You don’t need any legal vocabulary to sense something went wrong. You lived it.
When a delay led to permanent damage, this can amount to medical negligence. The injured person or their family may have legal options. In Florida, negligence claims generally must be filed within two years for causes of action arising on or after March 24, 2023, under Fla. Stat. §95.11. Medical-negligence claims also have their own presuit investigation steps. Florida also uses a shared-fault (comparative negligence) rule under Fla. Stat. §768.81. Deadlines are strict, so timing matters as much legally as it did medically.
It costs nothing to ask. You can request a free, confidential case evaluation to understand where you stand.

When to go to the emergency room — even now
Get to an emergency room right away if you develop new or worsening bladder or bowel trouble, spreading saddle numbness, or fast-worsening leg weakness. These are warning signs of acute cauda equina compression. Delay costs nerve function that may not come back.
This matters even for people already living with chronic CES. Symptoms can get worse again if new pressure develops. Don’t wait to “see if it passes.” An emergency MRI and surgery may be needed to protect the nerves you still have. This page is educational only.

Frequently asked questions
What is the difference between acute and chronic cauda equina syndrome?
Acute CES is a sudden surgical emergency. “Chronic” describes symptoms that last long-term. They come either from slow, gradual pressure on the nerves or as lasting problems that remain after emergency surgery.
What are the long-term complications of chronic cauda equina syndrome?
They can include repeated urinary tract infections, kidney problems, pressure sores, chronic nerve pain, and permanent disability affecting the legs, bladder, and bowel.
Can you still have symptoms after cauda equina surgery?
Yes. Surgery takes pressure off the nerves but may not undo existing damage. So weakness, numbness, and bladder or bowel problems can be permanent — especially after delayed treatment.
What is saddle numbness in cauda equina syndrome?
Saddle numbness (saddle anesthesia) is reduced or missing feeling across the buttocks, groin, and inner thighs — the areas a saddle would touch. It’s a key CES symptom.
Can a delayed diagnosis of cauda equina syndrome be the basis of a claim?
Possibly. If a delay in diagnosis, imaging, or surgery led to permanent damage, the injured person or family may have legal options worth discussing with an attorney.

Understanding the Condition
Acute vs. Chronic CES
Acute cauda equina syndrome is a sudden surgical emergency. 'Chronic' describes symptoms that persist long-term — either from slow, gradual pressure on the nerves or as lasting problems that remain after emergency surgery.
When Symptoms Linger After Surgery
Even when surgery relieves the pressure in time, some people are left with permanent nerve damage. These lasting deficits can require lifelong care, adaptive equipment, and ongoing medical support.
How Injury or Negligence Can Play a Role
CES can follow serious trauma, such as a truck or motor-vehicle crash, or worsen when a diagnosis is delayed. When a preventable failure caused permanent harm, a family may have a right to pursue compensation.
