When pain occurs at the junction of the arm and shoulder, different treatment methods should be used depending on the disease. If the pain is accompanied by restriction of shoulder movement in all directions and the symptoms persist for a period of time, the pain may be caused by frozen shoulder, which can be treated by massage to eliminate inflammation, reduce tissue adhesion, relieve tendon and Qi, and relieve pain. If the pain is severe, local closed treatment can be used directly to eliminate the pain once a week for three weeks, together with physical therapy such as Chinese medicine ionization, ultra-short wave therapy and electromagnetic therapy, the effect is also very obvious. If the pain is aggravated by lateral flattening of the arm, it is considered to be caused by subacromial bursitis. It is best to take Shu Tendon and Blood Soup or Gui Zhi Tang orally, and use compound Nan Xing Pain Relief Cream or hot compresses externally. If the pain is prolonged, cupping treatment can be used to help unblock the Qi and blood, and warm acupuncture treatment is more effective.
