What causes arm soreness, weakness, and hand tremors?

Generally speaking, arm soreness, weakness, and hand tremors may be caused by stress and anxiety, overexertion, tendon sheath inflammation, hyperthyroidism, cervical spondylosis, and other factors. Symptomatic treatment through general therapy and medication may be necessary. If physical discomfort occurs, prompt medical attention is advised to avoid delays in treatment. A detailed explanation is as follows:

1. Stress and Anxiety

Under conditions of stress and anxiety, the body releases increased levels of hormones such as adrenaline and cortisol, which can cause muscle tension and tremors, particularly noticeable in the hands. These symptoms may also be accompanied by palpitations, sweating, and sleep disturbances. It is recommended to learn and practice relaxation techniques such as deep breathing, meditation, and progressive muscle relaxation exercises.

2. Overexertion

Extended or high-intensity physical labor or exercise may lead to overuse of muscles, causing muscle fatigue or even injury. Overuse of the arm muscles may lead to lactic acid buildup, resulting in soreness, weakness, and even trembling. It is recommended to reduce activity appropriately, ensure adequate rest, and relieve muscle fatigue through heat compresses or massage.

3. Tendon Sheath Inflammation

Tendon sheath inflammation is often caused by prolonged rapid finger movements or rheumatoid arthritis, which may lead to muscle fascia strain, subsequently causing arm soreness and hand tremors. Symptoms may also include joint pain and stiffness in the fingers. It is recommended to follow medical advice in using medications such as celecoxib capsules, ibuprofen sustained-release capsules, and dexamethasone acetate tablets for treatment.

4. Hyperthyroidism

Autoimmune disorders, genetic factors, environmental influences, and other factors may lead to hyperthyroidism. Excessively high levels of thyroid hormones accelerate the body's metabolic processes and affect the stability of the neuromuscular system, leading to muscle weakness and hand tremors. Symptoms may also include palpitations, excessive sweating, and weight loss. It is recommended to follow medical advice in using medications such as methimazole tablets, propylthiouracil tablets, and carbimazole tablets to alleviate symptoms.

5. Cervical Spondylosis

Cervical spondylosis may be caused by improper sleeping posture, excessive neck movement, and other factors. Cervical spine lesions may compress nerve roots, affecting nerve signal transmission, causing weakened muscle strength and hand tremors. Symptoms often include neck pain, shoulder and back pain, and numbness in the fingers. It is recommended to follow medical advice in using medications such as aceclofenac tablets, Jingfukang granules, and mecobalamin tablets to alleviate symptoms.

It is advisable to avoid repetitive arm movements for prolonged periods in daily life. Take regular breaks during work or physical activity, and perform actions such as clenching fists and stretching to relieve muscle tension.
