Transverse Myelitis (TM)
Transverse Myelitis (TM)
Transverse Myelitis (TM) is a rare but serious neurological condition that occurs when inflammation damages the spinal cord. This inflammation disrupts communication between the brain and the rest of the body, leading to a wide range of symptoms that can affect movement, sensation, and organ function.
TM can appear suddenly and progress quickly, often leaving patients frightened and uncertain about what’s happening to their bodies.
How Transverse Myelitis Works
In TM, the body’s immune system mistakenly attacks the protective covering of nerve fibers in the spinal cord (called myelin). This immune attack causes swelling and interrupts the normal flow of electrical signals that carry messages from the brain to the rest of the body.
Depending on where the inflammation occurs, this can lead to weakness or paralysis in the arms or legs, severe back or nerve pain, loss of sensation, bladder or bowel problems, and difficulty regulating temperature or blood pressure. Some patients describe TM as feeling like a tight band around their torso, or as burning, tingling, or stabbing sensations that can come on rapidly.
Vaccine Connection
While the exact cause of TM is not always clear, medical researchers believe vaccine causation may result from an abnormal immune response — where the immune system, activated by a vaccine, mistakenly targets the body’s own nerve tissue instead of the intended antigens.
Treatment and Recovery
Treatment for TM usually focuses on stopping the inflammation and helping the body heal. Patients are often given high doses of intravenous steroids, plasma exchange, or immunosuppressant medications. Physical therapy and rehabilitation are essential to restore movement, strength, and independence.
Conclusion
If you or a loved one developed Transverse Myelitis after a vaccination, you may be entitled to compensation through the National Vaccine Injury Compensation Program (VICP). Our firm helps families file and pursue these claims with care and precision.

Transverse Myelitis is an inflammatory disorder of the spinal cord in which an immune-mediated process damages the myelin (the protective sheath around nerve fibers) and sometimes the nerve tissue itself.
The term “transverse” refers to a horizontal strip across the spinal cord segment, meaning that the inflammation often affects both sides of the cord at a particular level.
This inflammation interrupts or blocks the transmission of electrical signals between the brain and parts of the body below the lesion.
The result can be sensory, motor, and autonomic disturbances depending on the location and severity of the spinal cord involvement.
-
Although TM is rare, there are documented cases in medical literature of TM occurring after vaccination.
In those cases, the timing varies — typically from a few days up to several weeks or even months post-vaccination. This timing suggests a possible immune trigger.
The immune response triggered by a vaccination may misdirect against spinal cord components, leading to inflammation.
-
The onset of TM is typically sudden to subacute (hours to days, sometimes over a week or two).
Common symptoms include:
Weakness or paralysis in the legs, arms, or both (depending on where the spinal cord is affected).
Sensory disturbances: tingling, numbness, burning sensations, or abnormal sensations (“pins and needles”) below the lesion level.
Pain: often sharp, radiating pain in the back, chest, or limbs, or a band-like ache around the torso at the lesion level.
Bladder, bowel, or sexual dysfunction: urinary retention, incontinence, constipation, or difficulty controlling bladder/bowel function.
Sometimes autonomic (organ system) symptoms: problems with blood pressure or heart rate, or temperature regulation below the lesion.
Because TM can affect both sides of the body below the level of spinal involvement, you may feel a “belt” or level across your trunk where sensation changes.
-
There is currently no guaranteed “cure” for TM, but medical treatment aims to reduce inflammation, protect surviving nerve tissue, and support recovery.
Some common treatments include:
High-dose corticosteroids (e.g. methylprednisolone) given intravenously to reduce inflammation.
Plasma exchange (plasmapheresis) in more severe or steroid-resistant cases, to remove harmful antibodies from circulation.
Immunosuppressants / immunomodulatory therapy in some chronic or relapsing cases.
Rehabilitation: physical therapy, occupational therapy, and supportive care to regain strength, coordination, and daily functioning.
Symptom management: pain control, bladder or bowel management, spasticity control, etc.
Recovery is variable: some patients recover fully, many recover partially, and a minority have permanent residual deficits
-
The estimated incidence of acute transverse myelitis in the general population is about 1.3 to 4.6 cases per million people per year in adults.
In vaccine-linked TM, the latency (time between vaccination and onset) is often between days and weeks, though reports exist of onset up to three months after the administration of the vaccine.
