In clinical practice, frozen shoulder is a relatively common condition. If suffering from frozen shoulder causes pain in the whole arm, it means that the degree of frozen shoulder is more severe. Since severe frozen shoulder can involve pain in the arm, after this condition occurs, first of all, the patient should pay attention to keeping the shoulder warm and avoiding unfavorable factors such as cold and strain. Secondly, the shoulder can be closed and disposed of, or a small needle can be used to loosen and pry the shoulder joint and surrounding soft tissues to relieve the pain. You can also apply Fotarine spray on the shoulder to relieve the pain. After the shoulder pain is relieved, you can perform passive movement of the shoulder joint under the guidance of the massage therapist and then active movement of the shoulder joint. Therefore, it is crucial for the patient to seek timely medical attention after the occurrence of the above-mentioned condition, and the correct treatment should be taken after the doctor’s timely diagnosis so that the pain symptoms can be relieved as soon as possible.
