Hi, thanks for writing to HCM. Muscle twitches can happen for lots of reasons, like stress, too much caffeine, a poor diet, exercise or as a side effect of some medications. Although most twitches go away in a few days and are nothing to worry about, some twitches can be caused by nerve problems or other medical conditions. Getting enough sleep, avoiding too much caffeine, and eating healthy foods (like lots of fruits and vegetables), can help prevent some muscle twitches. You should consult a doctor if • you have a twitch that doesn t go away • you notice weakness, tingling, or numbness in the area where you get muscle twitches • it looks like the muscle is getting smaller Hope this information is helpful. Good day
