Malaise is a general term used to describe a state of being unhealthy or experiencing discomfort without a clear cause. This sensation may arise from transient and non-serious issues. However, in some cases, it may be associated with chronic or more severe medical conditions that require professional assistance and treatment.

Headaches can be a common symptom of disorders, dehydration, or certain chronic illnesses. Meanwhile, chronic fatigue may stem from conditions such as fibromyalgia, depression, or sleep disorders.
