Edit Shadow Key. A shadow key is an item found in gold chests in the dungeon. Shadow keys are required for unlocking a shadow chest. All shadow chests are originally found locked. Unlike a golden key, shadow keys are not consumed when unlocking a chest.
Muscle twitching, also known as muscle fasciculation, is marked by small muscle contractions in the body. Your muscles are composed of fibers, tissues, and nerves. When a nerve is stimulated or damaged, it may cause your muscle fibers to twitch. Many twitches experienced in your body are common and may go unnoticed.
January 11th, 2006. I keep getting these feelings, usually at night, of twitching and things moving under my skin or in the veins. Sometimes it's like a small twitching pulse, which has been in my legs, neck, face, and even lips. Other times it's like I can feel something thick moving through my veins or under my skin, like there's a little creature moving through them. My legs also twitch and occasionally jerk.
