What causes numbness and pain in the arm?

Arm numbness and pain is a common neurological symptom characterized by reduced or lost sensation and motor function in the skin of the arm, often accompanied by discomfort and pain. This pain may be severe, radiating upward or downward, or recurrent. Patients may present with varying responses; some may experience systemic discomfort such as irritability, headaches, or lower back pain. During consultation, the doctor will carefully take the patient's history and perform a thorough physical examination to rule out neurological and infectious diseases, while also considering neurological damage caused by trauma, malnutrition, or spinal disorders. For arm numbness and pain, patients may receive medication, physical therapy, or surgical treatment to relieve symptoms. Additionally, maintaining good stress management practices, along with a balanced diet and appropriate exercise, can help strengthen the body's resistance and alleviate pain.
