Sneezing arm pain is caused by muscle or nerve stimulation and pulling, common arm muscle strain, frozen shoulder, cervical spondylosis, etc., you should consult a doctor in time to find out the reason. 1. Arm muscle strain: arm muscles are relatively rich, prolonged heavy physical labor can easily lead to muscle strain, when sneezing, arm muscles are stimulated and pulled, resulting in muscle contraction, pulling the affected area, thus causing soreness. 2. Frozen shoulder: Frozen shoulder is caused by degeneration and adhesion of the soft tissues of the shoulder joint, which can lead to shoulder pain and restricted activities. When sneezing, the shoulder joint is stimulated by adverse stimuli, which can also trigger soreness in the arm. 3. Cervical spondylosis: If there is nerve root cervical spondylosis, there may be narrowing of the intervertebral foramina or the nerve root is extruded. When sneezing, the nerve root compression is aggravated, which will also cause radiating pain in the arm, and part of the person may have a feeling of weakness. When arm pain occurs after sneezing and cannot be relieved after resting, keeping warm and other self-conditioning, you should consult a doctor in time to find out the cause and actively cooperate with the doctor for treatment.
