Clinically, if a patient presents with pain when the right arm is lifted, there are a number of etiologies that can cause this. If the patient suffers from rotator cuff injury, when moving the arm, it pulls the shoulder muscles and produces pain. In addition, if the patient suffers from frozen shoulder, due to the adhesion of the shoulder joint muscles, when the patient moves his arm, the adhesion of the muscles stimulates the nerves and produces pain. In addition, if the patient suffers from cervical spondylosis, due to the spinal cord pressure stimulates the nerve roots on both sides, which will also lead to pain in the arm, but at the same time, there will be numbness and sensory loss in the upper arm and other symptoms. If the patient suffers from cysts in the axilla, due to the compression of the cysts on the tucked plexus nerves stimulating the nerve endings, the same pain is produced when moving the arm. Therefore, in the clinic, after the appearance of this phenomenon, the patient should consult the doctor in time. After the doctor confirms the diagnosis, and then take symptomatic treatment to avoid delaying the condition.
