Myelitis is a neurological condition that requires prompt diagnosis and treatment because it can directly affect the nerves' ability to transmit signals between the brain and the rest of the body. This inflammation may cause a variety of symptoms that often begin mildly and gradually worsen over several hours or days, although in some cases they can appear suddenly.
Recognizing the symptoms of myelitis early is essential, as timely medical intervention can help minimize nerve damage, improve recovery outcomes, and reduce the risk of long-term complications such as muscle weakness, loss of sensation, or bladder and bowel dysfunction.
In this article, we will discuss the symptoms of myelitis in detail, how they develop, their causes, when the condition becomes a medical emergency, available diagnostic methods and treatment options, and answer some of the most frequently asked questions.
What Is Myelitis?
Myelitis is an inflammation of the spinal cord, the part of the central nervous system responsible for transmitting nerve signals between the brain and the rest of the body. When inflammation affects the spinal cord, it can damage the nerve fibers or their protective covering (myelin), disrupting normal movement, sensation, and the function of certain organs.
The inflammation may affect a small section of the spinal cord or extend across multiple segments. As a result, symptoms vary depending on the location, severity, and underlying cause of the inflammation.
Possible causes include viral or bacterial infections, autoimmune diseases, complications following infections, or, in some cases, the exact cause remains unknown.
How Do the Symptoms of Myelitis Begin?
In most cases, symptoms do not appear all at once. They often begin gradually, with mild pain in the neck or back, followed by tingling or numbness in the arms or legs. As the condition progresses, muscle weakness and difficulty moving may develop.
Some patients experience rapid progression within a few hours, while others develop symptoms over several days. Any sudden neurological changes should be evaluated by a healthcare professional immediately.
Symptoms of Myelitis
Several symptoms commonly occur in people with myelitis, including:
Back or Neck Pain
Back pain is one of the most common early symptoms. The pain may be sharp or persistent and often becomes worse with movement or over time.
The pain may radiate to:
-
The arms
-
The legs
-
The chest
-
The abdomen
Many patients describe the pain as burning or similar to electric shock sensations.
Muscle Weakness
Inflammation affects the nerves responsible for movement, causing gradual muscle weakness.
Patients may experience:
-
Difficulty walking
-
Trouble climbing stairs
-
Weak hand grip
-
Fatigue during physical activity
-
Difficulty standing for long periods
In severe cases, weakness may progress to partial or complete paralysis.
Numbness and Tingling
One of the earliest warning signs is numbness or tingling in:
-
The feet
-
The legs
-
The hands
-
The arms
Some patients also lose the ability to distinguish between hot and cold temperatures or notice complete numbness in certain parts of the body.
Loss of Sensation
People with myelitis may lose their ability to feel pain, touch, or temperature below the level of spinal cord inflammation.
The greater the inflammation, the larger the affected area.
Difficulty Walking
Many patients develop walking difficulties due to muscle weakness or impaired balance.
Common symptoms include:
-
Dragging one or both feet
-
Poor balance
-
Frequent falls
-
Slow walking
-
Needing assistance while walking
Loss of Balance
Patients may experience unsteadiness even while standing still because the inflammation interferes with the nerves responsible for body position awareness.
Muscle Spasms
Painful muscle spasms or stiffness may develop in the arms or legs, affecting daily activities.
Many patients also report constant muscle tightness.
Bladder Problems
Inflammation of the spinal cord can affect the nerves controlling the bladder, leading to:
-
Difficulty urinating
-
Urinary retention
-
Frequent urination
-
Loss of bladder control
These symptoms require prompt medical attention.
Bowel Problems
Some patients may experience:
-
Constipation
-
Difficulty passing stool
-
Loss of bowel control in severe cases
Band-Like Tightness
Some individuals describe a sensation of a tight band wrapped around the chest or abdomen. This is considered one of the characteristic symptoms of myelitis.
Symptoms Based on the Location of Inflammation
Cervical (Neck) Myelitis
Inflammation affecting the cervical spinal cord may cause:
-
Weakness in both the arms and legs
-
Hand numbness
-
Difficulty using the fingers
-
Balance problems
In severe cases, breathing may also be affected.
Thoracic (Mid-Back) Myelitis
Inflammation in the middle portion of the spinal cord may lead to:
-
Leg weakness
-
Chest pain or tightness
-
Numbness below the level of inflammation
-
Bladder dysfunction
Lumbar (Lower Back) Myelitis
When the lower spinal cord is affected, patients may experience:
-
Foot numbness
-
Leg weakness
-
Difficulty walking
-
Urinary problems
Causes of Myelitis
Several conditions can trigger spinal cord inflammation, including:
-
Viral infections
-
Bacterial infections
-
Autoimmune diseases
-
Multiple sclerosis (MS)
-
Neuromyelitis optica (NMO)
-
Systemic lupus erythematosus (SLE)
-
Post-infectious inflammatory reactions
In some cases, no definite cause can be identified.
Who Is More Likely to Develop Myelitis?
Although myelitis can affect anyone, it is more common among:
-
People with autoimmune disorders
-
Individuals recovering from recent infections
-
Young and middle-aged adults
-
Patients with a history of neurological diseases
How Are the Symptoms of Myelitis Diagnosed?
Diagnosis usually involves:
-
Medical history evaluation
-
Neurological examination
-
Magnetic Resonance Imaging (MRI)
-
Cerebrospinal fluid (CSF) analysis
-
Blood tests
-
Autoimmune testing
These investigations help determine the underlying cause and rule out other neurological conditions.
Treatment for Myelitis
Treatment depends on the underlying cause and the severity of the condition.
Corticosteroid Therapy
High-dose corticosteroids are commonly used to reduce inflammation quickly and limit nerve damage.
Plasma Exchange Therapy
Plasma exchange (plasmapheresis) may be recommended for patients who do not respond adequately to steroid treatment.
Immunotherapy
Patients with autoimmune-related myelitis may require medications that suppress or regulate the immune system.
Physical Therapy
Physical rehabilitation plays a crucial role in recovery by helping to:
-
Improve mobility
-
Strengthen muscles
-
Restore balance
-
Reduce muscle stiffness
Neurological Rehabilitation
Rehabilitation programs aim to help patients regain independence and improve their ability to perform daily activities.
Can Patients Recover from Myelitis?
Recovery depends on several factors, including:
-
How quickly treatment begins
-
The severity of inflammation
-
The underlying cause
-
The extent of nerve damage
Some patients recover completely, while others require months of rehabilitation and may continue to experience varying degrees of residual symptoms.
Complications of Myelitis
Without early treatment, myelitis may lead to complications such as:
-
Permanent muscle weakness
-
Difficulty walking
-
Chronic nerve pain
-
Bladder dysfunction
-
Bowel dysfunction
-
Muscle spasticity
-
Reduced quality of life
