You Have A Lot Of Nerve (s).
The nerves in our bodies are like cables that carry electrical impulses between your brain and the rest of your body. These impulses help you feel sensations like pain, temperature, fine touch, etc and move your muscles. Every muscle in our body is supplied by certain nerves. Disruption of these nerve paths such as impingement, injury, or severed nerve can cause issues to surrounding muscles, like numbness, tingling, no activation, sharp pain.
