Causes of Body Ache

The list of things that can make your whole body ache is long - but the everyday causes account for almost all of it. Here is the map, from the common to the must-not-miss.

The everyday causes

• Viral infections: the classic cause. Flu, common colds, dengue, chikungunya, COVID - immune signalling chemicals produce the all-over ache, usually with fever, sore throat or runny nose
• Overexertion: unaccustomed exercise, heavy lifting, a long day of physical work. Delayed soreness peaks 24-72 hours later and resolves on its own
• Poor sleep: even a few nights of short or broken sleep measurably lowers pain thresholds
• Dehydration and heat: especially in Indian summers, with cramps and heaviness
• Stress and anxiety: sustained muscle tension, especially neck, shoulders and back
• Prolonged sitting or bad posture: the desk-work ache

Deficiencies and medical causes

• Vitamin D deficiency: extremely common in India; causes diffuse aching and fatigue
• Vitamin B12 deficiency, low iron, thyroid underactivity: each can present as persistent ache with tiredness
• Fibromyalgia: chronic widespread pain with unrefreshing sleep and fatigue, diagnosed after excluding other causes
• Infections beyond the usual: dengue and chikungunya (seasonal, with fever), typhoid, and others
• Medication side effects: statins are the classic example
• Inflammatory conditions: polymyalgia rheumatica in people over 50 (shoulder and hip girdle aching with morning stiffness), rheumatoid arthritis and others
• Rhabdomyolysis: muscle breakdown after extreme exertion, heat stroke or certain drugs - dark, cola-coloured urine is the warning sign and an emergency

The MedlinePlus overview of muscle aches covers this same spectrum well.

The classical view

The classical causes of Angamarda read like a commentary on the modern list: overexertion beyond one's capacity (Vyayama and load-carrying), Vata-provoking cold and dry exposure, Ama from weak digestion, and - centuries before sleep science - suppression of sleep and hunger as direct causes of body pain (Ashtanga Hridaya, Sutra Sthana 4). The framework is traditional and interpretive; persistent or unexplained ache still belongs to blood tests and a doctor, not to theory.
