Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time. It can be associated with astate of exhaustion, often following strenuous activity or exercise. When you experience fatigue, the force behind your muscles’ movements decrease, causing you to feel weaker.

Your doctor will evaluate your medical history and symptoms to rule out more serious health conditions.

Muscle fatigue decreases the amount of force you use to perform muscle actions. This symptom is often considered no cause for alarm unless your fatigue doesn’t improve with rest.

If your muscle fatigue is paired with other irregular symptoms or if your condition doesn’t improve after a few days, schedule a visit with your doctor.
