Transverse Myelitis: Recovery and Living With It

What transverse myelitis is

The spinal cord carries signals between the brain and the body. In transverse myelitis, inflammation damages the insulating myelin and nerve fibers across the width ("transverse") of the cord at one level, most often in the chest (thoracic) region. Everything below that level can be affected: movement, sensation, and bladder, bowel and sexual function.

It is rare, affecting a few people per million each year, and can occur at any age. Our acute transverse myelitis page covers the emergency phase in detail. This page focuses on the cause work-up, recovery and life afterward.

Symptoms

Symptoms develop over hours to days and peak within about 3 weeks:

• leg weakness, sometimes arms too if the neck is involved
• numbness, tingling, burning or reduced sensation below a level on the trunk
• a tight band or girdle sensation around the chest or abdomen
• back or neck pain
• urinary urgency, incontinence or retention
• constipation
• sexual dysfunction

Complete transverse myelitis affects both sides fully. Partial transverse myelitis is milder or uneven, affecting one side or certain sensations more.

Causes and why they matter for relapse

Doctors look hard for a cause, because it predicts whether TM will return and how to prevent it.

Partial transverse myelitis with brain lesions on MRI carries a high chance of later developing MS. That is why follow-up brain MRI is often repeated.

How it is diagnosed

• MRI of the spine and brain with contrast to confirm cord inflammation and look for MS-type lesions.
• Spinal tap to check for inflammatory cells, oligoclonal bands and infection.
• Blood tests for AQP4 and MOG antibodies, autoimmune markers, vitamin B12, copper, HIV, syphilis and other infections.
• MRI first to exclude compression of the cord from a disc, tumor, abscess or bleeding, which needs surgery.

Doctors also distinguish TM from Guillain-Barré syndrome, which affects peripheral nerves, and from spinal cord strokes.

Acute treatment

• IV methylprednisolone for 3 to 7 days, sometimes followed by oral steroids.
• Plasma exchange for severe weakness or if steroids do not help.
• Other immune therapies such as IV immunoglobulin or cyclophosphamide in selected cases.
• Antivirals or antibiotics if an infection is found.

Recovery: what to expect

• Recovery usually begins within 2 to 12 weeks of onset.
• The fastest gains occur in the first 3 to 6 months, and improvement can continue for up to 2 years.
• A traditional rule of thumb: about a third of people recover with little or no disability, a third have moderate disability and a third have severe disability.

Recovery tends to be slower or less complete when symptoms came on very rapidly, there was severe back pain, complete paralysis or "spinal shock" (loss of reflexes and tone), or the lesion was very long.

Rehabilitation

Inpatient or outpatient rehabilitation should start early. Physical therapy rebuilds strength, balance and walking. Occupational therapy helps with daily tasks, home adaptations and equipment. Many people use canes, braces (such as ankle-foot orthoses) or wheelchairs, at least for a time.

Long-term effects and how they are managed

• Nerve pain: burning, stabbing or band-like pain is common. Gabapentin, pregabalin, duloxetine or amitriptyline can help.
• Spasticity and spasms: stiffness and jerking in the legs, treated with stretching, baclofen, tizanidine or botulinum toxin injections. See muscle spasms.
• Bladder problems: a neurogenic bladder may cause urgency, leakage or incomplete emptying. Treatments include bladder medicines, intermittent self-catheterization and Botox injections into the bladder.
• Bowel problems: a bowel routine with fiber, fluids, laxatives or suppositories.
• Sexual dysfunction: treatments are available for both men and women.
• Fatigue: pacing, sleep, exercise and treating mood.
• Heat sensitivity: old symptoms may flare temporarily with heat or fever.
• Depression and anxiety: common after sudden disability, and treatable.

Preventing relapse

If an underlying disease is found, long-term treatment lowers relapse risk: disease-modifying therapy for MS, and specific preventive treatments for NMOSD such as eculizumab, inebilizumab, satralizumab or rituximab. Most people with idiopathic TM never have another episode, but any new symptoms should be reported promptly.

Frequently asked questions

How long does it take to recover from transverse myelitis?

Recovery usually begins within 2 to 12 weeks after symptoms start. Most improvement happens in the first 3 to 6 months, but some people keep improving for up to 2 years. How far recovery goes varies widely between people.

What are the long-term effects of transverse myelitis?

Common lasting effects include nerve pain, leg stiffness and spasms, weakness, numbness, bladder and bowel problems, sexual dysfunction and fatigue. Some people recover almost completely, while others need long-term walking aids or a wheelchair. Most effects can be improved with treatment and rehabilitation.

Can transverse myelitis come back?

After a single episode with no underlying cause, recurrence is uncommon. Relapse is more likely when TM is caused by multiple sclerosis, neuromyelitis optica spectrum disorder, MOG antibody disease or a systemic autoimmune disease. Preventive treatment reduces that risk.

Is transverse myelitis the same as MS?

No, but they are linked. Transverse myelitis can be the first sign of multiple sclerosis, especially when it is partial and brain MRI shows other lesions. Many people with TM never develop MS. Follow-up MRI scans help clarify the risk.

Why does transverse myelitis cause pain?

Inflammation damages nerve fibers in the spinal cord that carry sensation. The damaged pathways can send faulty pain signals, causing burning, stabbing, tingling or a tight band-like feeling. This neuropathic pain responds better to nerve pain medicines than to standard painkillers.
