Soreness in both arms is a symptom that occurs in many people, but it does not mean that it is early stage cancer. Soreness in both arms may be caused by long-term exertion, or short-term squeezing or bumping, or muscle soreness after strenuous exercise, or even some patients suffering from arthritis or cervical spondylosis may experience soreness in both arms. Patients can initially determine what causes it based on their usual habits, or they can go to the hospital for an arm examination to further clarify the real cause of arm soreness through the judgment of a professional doctor. Patients with arm pain are advised to rest for a few days to avoid arm strain, apply heat to the area to relieve the pain, and also apply blood-stimulating and pain-relieving ointment. If the symptoms are not relieved, further examination and treatment at the hospital is required.
