Step-by-step explanation:
Guillain-Barré Syndrome
Based on the patient's symptoms of numbness in the feet that progressed up the legs and caused paralysis, the disease they are experiencing is Guillain-Barré Syndrome (GBS). GBS is a demyelinating disease of the peripheral nervous system that results from an autoimmune reaction. In GBS, the inflammation occurs in the peripheral nerves, leading to sensory symptoms, motor deficits, and autonomic failures.
