Question: What causes muscle twitches?
Answer:
For most people, muscle twitches are fairly normal and are usually caused by a single nerve that serves a group of muscles. These twitches can be triggered by stress, anxiety, caffeine, exercise, or the side effect of drug use or an overdose.
For other people, it can be the sign of a more serious condition, such as an autoimmune disorder or nervous system disorder, such as muscular dystrophy, nerve damage, myopathy or ALS.
