Whole-body muscle aches and feeling drowsy and lethargic

Generalized muscle aches and mental fogginess may be caused by physiological factors, or could result from pathological conditions such as upper respiratory tract infections or insufficient cerebral blood supply. Patients can improve their condition through general treatments, medications, and other approaches. The specific analysis is as follows:

1. Physiological Causes

When patients are excessively fatigued or chronically sleep-deprived, large amounts of lactic acid may accumulate in the muscles. Without adequate rest, the body cannot effectively metabolize and eliminate lactic acid, potentially leading to generalized muscle pain accompanied by feelings of mental fogginess. Taking hot showers and ensuring sufficient sleep can help alleviate these symptoms.

2. Pathological Causes

a. Upper Respiratory Tract Infection

When the body's resistance decreases, external viruses and bacteria may rapidly multiply. Factors such as exposure to cold or excessive stress can also trigger this condition, resulting in symptoms including fever, headache, dizziness, muscle aches, and nasal congestion. Patients may follow medical advice to take medications such as ibuprofen capsules, oseltamivir phosphate capsules, or acetaminophen tablets to relieve symptoms.

b. Insufficient Cerebral Blood Supply

Inadequate blood flow to the brain can cause mental fogginess. Due to insufficient blood supply, the brain and other organs and tissues may experience hypoxia and ischemia, potentially leading to symptoms such as generalized muscle pain, fatigue, and dizziness. Patients should follow medical guidance and may take medications such as enteric-coated aspirin tablets or betahistine hydrochloride tablets to improve their condition.

Besides the above-mentioned causes, similar symptoms may also be related to influenza, neurasthenia, or neuritis. If symptoms are severe, patients are advised to seek timely medical attention and undergo thorough examinations.
