Muscles can sometimes vibrate, jitter, tremor or shake when they are used or moved. This can be a symptom of anxiety disorder, including during anxiety and panic attacks. Muscle vibrations can also be a symptom of stress, which can cause the body to remain in a state of semi stress response readiness, or 'hyperarousal'. Muscle vibrations can range in intensity from slight to severe, and can come and go rarely, occur frequently, or persist indefinitely.

What You'll Learn
Muscles vibrate during anxiety and panic attacks
Muscle shakes, jitters, tremors and vibrations can range in intensity from slight to moderate to severe. They can occur when raising or lowering an arm or leg, or when using the hands, fingers, feet or toes. Even if you are not experiencing muscle twitches or tremors when still, you may notice them when you are moving around or using your muscles.
Muscle vibrations, jitters, tremors and shakes are often symptoms of anxiety disorder, including during anxiety and panic attacks. When stress responses occur infrequently, the body can recover relatively quickly from the physiological, psychological and emotional changes. However, when stress responses occur too frequently, the body doesn't completely recover. This can result in the body remaining in a state of semi stress response readiness, which is called "stress-response hyperstimulation" or "hyperarousal". A body that becomes hyperstimulated can exhibit all of the changes of an active stress response even though a stress response hasn't been activated.

Muscle vibration can be a symptom of stress
Muscle vibration can also occur during anxiety and panic attacks. For example, you may experience shaking, tremors, vibrating or jitteriness when raising or lowering an arm or leg. You may notice your arms, legs, hands, fingers, feet or toes are shaky when you use them.
A part of the stress response includes body-wide stimulation and tense muscles. This combination can cause muscles to shake, vibrate, jitter or tremor when used. When stress responses occur too frequently, the body doesn't completely recover. This can result in the body remaining in a state of semi-stress response readiness, which is called "stress-response hyperstimulation" since stress hormones are stimulants. A body that becomes hyperstimulated can exhibit all of the changes of an active stress response even though a stress response hasn't been activated.

Muscle vibration can also be caused by stress responses. When stress responses occur infrequently, the body can recover relatively quickly from the physiological, psychological, and emotional changes the stress response brings about. When stress responses occur too frequently, however, the body doesn't completely recover. This can result in the body remaining in a state of semi-stress response readiness, which is called "stress-response hyperstimulation" since stress hormones are stimulants. A body that becomes hyperstimulated can exhibit all of the changes of an active stress response even though a stress response hasn’t been activated.

Muscle vibration can be a symptom of nervousness, fear, or elevated stress
Muscle vibration can occur when a muscle or muscle group is used or moved, for example, when raising or lowering an arm or leg. It can also occur when you are still and not using your muscles. Muscle vibration can come and go rarely, occur frequently, or persist indefinitely. It can also come in waves, where it is strong one moment and eases off the next. This symptom can change from day to day and from moment to moment.
Muscle vibration is often involuntary, meaning there is not much you can do to stop it. However, some people may be able to control their muscle vibration by calming themselves or by tightening and loosening their muscles. Muscle vibration can also be a symptom of stress-response hyperstimulation, where the body remains in a state of semi-stress response readiness. This can occur when stress responses occur too frequently, and the body does not completely recover from the physiological, psychological, and emotional changes that stress brings about.
