Cervical spondylosis can be treated with oral ibuprofen and other medications during the acute stage of left shoulder pain, physical therapy such as hot compresses during the symptomatic relief period, and surgery when the symptoms are severe. 1. Hot compresses: Patients with cervical spondylosis who work with their heads down for a long time or are exposed to cold can cause muscle spasms in the left shoulder, which can lead to pain. During the period of pain relief, the left shoulder can be massaged or localized hot compresses can be applied to relieve muscle spasm. It is forbidden to apply hot compresses, massage and other physical therapy during acute pain. 2. Medications: Non-steroidal anti-inflammatory drugs such as ibuprofen and celecoxib help to fight inflammation and relieve pain in the left shoulder. Vitamin B12 and other drugs can nourish the nerves, eliminate edema and relieve pain. 3. Surgery: If the above treatment is ineffective and the symptoms are severe, surgery is needed. The medication should be administered according to the doctor’s prescription. If the patient’s cervical spondylosis symptoms are serious, or if the symptoms persist without improvement, he/she should go to the hospital in time for treatment.
