These symptoms can have several causes, such as stress, poor sleep, nutritional deficiencies, thyroid or hormonal imbalances, or musculoskeletal problems. Infections or chronic conditions like anaemia (low red blood cell count) or fibromyalgia (a condition that causes widespread muscle pain) may also contribute. Eating a balanced diet rich in vitamins and minerals, staying hydrated, and getting adequate rest and sleep may help. If these symptoms persist, worsen, or affect your daily life, please consult a doctor for proper evaluation and treatment.
