This month is Multiple Sclerosis, or MS, awareness in many countries around the globe. But what exactly is MS?

AsapSCIENCE explains that millions of people suffer from the auto-immune disease where their own immune system attacks the myelin sheaths protecting neuron axons. This results with a build up of scar tissue, distorting neurological messages. 

This is one reason why many MS patients suffer from neurological pain or even tremors.
