Muscle twitches can be a source of irritation and concern for many people. These involuntary movements, known medically as myoclonus, manifest as sudden, rapid, brief jerking of a muscle or group of muscles. There are various factors that may contribute to muscle twitching. Micronutrient imbalances, whether due to reduced or high levels, can lead to such twitches. Hormonal imbalances, including those affecting thyroid or cortisol levels, can also alter the excitability of nerves and muscles, causing twitching. Medications are another potential cause, as they can change the ions in our body, affecting pH levels.
Interestingly, the twitches and cramps often felt by individuals may not necessarily originate in the muscles themselves. According to Jacobson, these persistent symptoms are likely caused by irritated nerves. These sensations can be accompanied by tingling and may affect just one part of the body or several areas.
Neurological disorders are a significant area of concern when it comes to myoclonus, as many different conditions can lead to these shock-like movements. Such movements may be the result of sudden muscle contractions, known as positive myoclonus, or sudden losses of muscle tone, which is referred to as negative myoclonus.
Peripheral neuropathy is another condition associated with muscle twitching, characterized by symptoms such as weakness, muscle cramps, twitching, pain, numbness, and burning or tingling sensations, often in the feet and hands. These symptoms relate to the type of affected nerve and can develop over days, weeks, or even years. Neuropathic pain, which can arise from peripheral neuropathy, is notably challenging to control and can significantly impact emotional well-being.
Specific syndromes, like Action myoclonus–renal failure (AMRF) syndrome, involve episodes of myoclonus and can be associated with kidney disease. However, not everyone with AMRF syndrome experiences kidney issues. Cramp-fasciculation syndrome (CFS), identified by the American Academy of Neurology, accelerates nerve activity, causing chronic muscle contractions, spasms, twitches, or cramps in parts of the body like the legs.
Hemifacial spasm (HFS) is a neurological disorder causing twitching on one side of the face due to involuntary contractions of the eyelid and other facial muscles. It often starts around one eye and can spread to the mouth and neck muscles on the same side.
