The phenomenon of pain occurs when the right arm goes backwards and upwards in the back, and the onset is mostly due to the patient suffering from frozen shoulder. As the muscles and soft tissues around the shoulder are damaged and muscle adhesions occur, the first thing that happens is that the patient feels pain in the shoulder joint area, and the pain is heavier at night, affecting sleep and the range of motion of the shoulder joint. In the treatment, you can take conservative treatment by telling the patient not to get cold in the shoulder joint area, pay attention to keeping warm, and give local hot compress treatment. You can also apply ointment to relieve blood stasis, reduce swelling and pain, or you can perform physiotherapy, low and medium frequency electrotherapy, or functional exercises for the shoulder joint under the guidance of a rehabilitation doctor to relieve the pain and improve the range of motion of the shoulder joint.
