NERVOUS TISSUE
PART 7 OF 7
Lifetime neuro problem list, finally read together: a symmetric, sensory-predominant neuropathy with slowed conduction and anti-MAG antibodies — present before the crash. Dismissed as “pinched nerve from the accident.”

Put your money down: One-sided accident, or two-sided disease?
A one-sided accident, or a two-sided disease — which reading does the whole nerve chart support?
Pick the answer you believe now. We’ll come back to it later!
A One-Sided Crash Can’t Explain This
Put Stina’s nerve story on one page. A year of symmetric foot numbness she explained away. A crash that seemed to start everything but only amplified it. Conduction studies showing not a severed wire but a uniformly slow one. Sensory loss far outrunning any weakness. And, on bloodwork, antibodies against MAG. Each finding alone earned a shrug; the crash gave everyone a tidy story to stop at. Lined up, they refuse that story. A one-sided accident does not produce symmetric, slowly progressive numbness that began the year before it happened.

A Nerve Disease, Not an Injury
Read together, this is a symmetric, antibody-associated (anti-MAG), sensory-predominant neuropathy with slowed conductionThe transmission of nerve impulses along neurons. — a peripheral nerve disease, not an injury. And in a patient with lifelong autoinflammation, that is not a coincidence sitting beside her FMF; it is her FMF, reaching the peripheral nervesNerves that extend beyond the brain and spinal cord.. The chronic immune activation that drove her rashes, her fevers, and her bone and muscle findings also fostered antibodies that loosened her myelin from the inside. The crash was real, and her pain is real — but the dismissal, “pinched nerve from the accident,” mistook an amplifier for a cause.

The Fire Enters the Wiring
The fire has left the blood and entered the wiring. And the numbness it left behind maps to L4/L5, the exact level where the Spinal Cord module will find the disc.

FINDING!
Radiating Leg Pain & Numbness After a ‘Clear’ Crash — a Wiring Problem
Read together, the nerve chart is one disease: a symmetric, sensory-predominant neuropathy with slowed conduction and anti-MAG antibodies, present on both sides and pre-dating the crash. A one-sided accident cannot produce it.
Confirm or refute your bet: One-sided accident, or two-sided disease?
A one-sided accident, or a two-sided disease — which reading does the whole nerve chart support?
Now that you’ve read the story, confirm or overturn it — step by step, with the evidence in hand.
