If the shoulder joint is painful and cannot be lifted, it is more likely to be caused by frozen shoulder.
You can apply local hot compresses, apply topical pain relief cream or Tianhe Bone Tong paste, as well as flurbiprofen or loxoprofen paste, and take Celecoxib capsules, or compound Seron capsules, chasing wind and penetrating bone pills orally, and supplement with massage, tui-na and physiotherapy.
If the symptoms do not improve, further investigations such as x-rays as well as magnetic resonance imaging are recommended to clarify the diagnosis before further management.
