Guillain-Barré syndrome is a rare but serious auto-immune disorder in which the immune system attacks healthy nerve cells in your peripheral nervous system (PNS). This leads to weakness, numbness, and tingling, and can eventually cause paralysis.
Normally, the immune system attacks germs in the body. However, with this disease, the immune system attacks nerves in the body. It is unclear why this happens.
This can be triggered by infections, vaccinations, surgery, medical procedures or injury.
