Severe muscle pain in the hands can sometimes be related to high uric acid, cholesterol-related metabolic problems, muscle strain, vitamin deficiency, arthritis, nerve irritation, or side effects of certain medicines. Borderline high uric acid may contribute to joint or muscle discomfort in some people, especially if there is swelling, stiffness, or pain in the fingers and joints. Poor sleep, stress, dehydration, and lack of physical activity may also worsen body pain. Improvement usually focuses on reducing inflammation and correcting contributing factors. Adequate hydration, regular stretching, gentle exercise, proper sleep, and reducing excess alcohol, red meat, oily food, and sugary drinks may help improve both uric acid and cholesterol levels gradually. Pain-relieving medicines or vitamin correction may also help, depending on the exact cause of the muscle pain. Persistent swelling, weakness in the hands, numbness, severe stiffness, or repeated attacks of joint pain may need further evaluation to check for gout, arthritis, nerve problems, or muscle-related conditions.
