Shell shock was one of the major side effects of WWI. Many soldiers suffered from it, as it was caused by the heavy explosions and constant fighting associated with the war. Troops suffering from shell shock struggled with sleep. They panicked on hearing gunshots, loud noises, shouting and similar. Sometimes it affected their ability to walk and talk. Shell shock was a scary thing.

Shell shock usually applies to WWI. After that war, a similar illness became known as “combat stress reaction.” So what exactly does it do to you? What are the symptoms?
