Patients with soreness in the forearm muscles of the hand are often due to the presence of hand overactivity, poor posture, trauma, and other etiologies. The specific etiologies are as follows: 1. Hand overactivity. This condition is common in patients who are manual laborers or fitness exercisers. This type of patients may be due to long-term use of the hand for force generation, such as repeated hand grasping activities, and then lead to excessive fatigue of the muscles of the forearm. This will cause localized soreness. 2. Poor posture. Some patients may be highly stressed or need to carry out some special work, resulting in the hand and forearm for a long time to maintain in a bad posture, which will cause excessive fatigue of the forearm muscles, or even produce muscle spasm, which will lead to soreness. 3. Trauma. If the patient suffers from pulling injury around the wrist joint, or is squeezed, hit and so on at the forearm, it will lead to the muscle of the forearm strained or bruised, which will also cause the above symptoms. Cervical spondylosis caused by cervical disc herniation or spinal stenosis compression of the cervical nerve roots innervating the forearm can also cause pain manifestations, it is recommended that the patient in the occurrence of the above symptoms should go to the orthopedic department in a timely manner to improve the relevant examination, under the guidance of the doctor for symptomatic treatment.
