Symptom #6: Fatigue
Fatigue is defined as the gradual feeling of tiredness that can be alleviated with rest. It can be divided into physical or mental fatigue where physical fatigue refers to the transient inability to maintain optimal physical performance. Mental fatigue occurs when there is a temporary inability to achieve maximal cognitive performance.
Fatigue can manifest as lethargy or somnolence. It is a very common symptom that can be seen in many situations such as inadequate sleep, nutritional deficiency, stress, overworking, dehydration, infections, and more. In polymyositis, physical fatigue occurs as there is often bilateral proximal muscle weakness causing difficulties with daily activities.
