Muscle twitches can be a source of annoyance or concern for many. The Ohio State Medical Center notes that stress, anxiety, and lack of sleep are common causes of muscle twitching. These conditions can alter the body’s chemistry, leading to involuntary twitches. Ryan Jacobson, MD, a neuromuscular specialist at RUSH University Medical Center, advises that while most twitches are not worrying, they can sometimes indicate more serious health issues, therefore consulting a physician is advisable. Stanford Medicine describes myoclonus as sudden, involuntary jerking of a muscle or a group of muscles, which can be a symptom of various neurological disorders. According to Baylor Medicine, the involuntary muscle contractions known as fasciculations can be signs of cramp-fasciculation syndrome (CFS), particularly affecting the legs. Harvard Health suggests stretching and heating as remedies for muscle cramps, such as those in the hamstring.

For those experiencing episodes of involuntary muscle jerking, the term action myoclonus–renal failure (AMRF) syndrome might come up, which is associated with kidney disease and myoclonus. Understanding these various conditions and their symptoms is crucial for identifying when medical advice is necessary.
