Describe your assessment plan for this patient (olecranon bursitis versus joint synovitis).

1. A 46-year-old man comes to you complaining of diffuse left elbow pain. When he carries a briefcase for three or four blocks, his elbow becomes stiff and sore. When he picks up things with his left hand, the pain increases dramatically. Describe your assessment plan for this patient (lateral epicondylitis versus osteoarthritis).

2. A 31-year-old man comes to you complaining of posterior elbow pain. He says he banged his elbow on the table 10 days earlier, and he has had posterior swelling for 8 or 9 days. Describe your assessment plan for this patient (olecranon bursitis versus joint synovitis).
