Patient presents with complaints of right shoulder pain, consistent with right shoulder impingement syndrome.  Symptoms include pain with overhead activities, difficulty sleeping on the affected side, and a feeling of weakness or catching in the shoulder.  Onset of pain was gradual, reported as approximately three weeks ago, and is exacerbated by reaching, lifting, and abduction.  Patient denies any specific injury or trauma.  Physical examination reveals tenderness to palpation over the right subacromial space, positive Neer and Hawkins-Kennedy impingement tests, and limited active range of motion in flexion, abduction, and external rotation compared to the left shoulder.  Strength testing of the right shoulder reveals mild weakness in abduction and external rotation.  No sensory deficits were noted.  Differential diagnosis includes rotator cuff tear, bicipital tendinopathy, and adhesive capsulitis.  Assessment: Right shoulder impingement syndrome.  Plan: Conservative management with rest, ice, and over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen.  Patient education provided on activity modification and proper body mechanics.  Referral to physical therapy for range of motion exercises, strengthening, and modalities such as ultrasound.  Follow-up scheduled in four weeks to assess response to treatment.  If symptoms persist, consider further imaging such as an MRI of the right shoulder to evaluate for rotator cuff pathology.  ICD-10 code M75.11 Right shoulder impingement syndrome.
