1. Guillain-Barré syndrome
Guillain-Barré syndrome (GBS) is a rare autoimmune disorder that happens when your immune system attacks your nerves, causing weakness and tingling that typically begins in the legs and feet. The weakness can spread quickly and eventually paralyze your entire body if not treated right away.
Aside from sudden leg weakness, other GBS symptoms include severe pain that worsens at night, prickling or needles or pins sensations in your fingers, ankles, wrists, and toes, problems controlling your bowels or bladder, and difficulty with eye or facial movements.
It’s still unknown what causes GBS, but an infection, such as respiratory or stomach flu, usually triggers it. See a doctor right away if you have any of these symptoms. While there’s no cure for Guillain-Barré syndrome, there are treatments that can relieve symptoms and reduce the duration of the illness.
