An 83‐year‐old man with multiple medical problems, including gout, pseudogout, and renal insufficiency, presented with more than a year of proximal weakness. He had an extensive previous medical workup, including a normal creatinine kinase. His weakness persisted despite endurance and strength training. Electrodiagnostic findings were consistent with a myopathy, although without abnormal spontaneous activity and a length‐dependent neuropathy. On the basis of these findings, colchicine was discontinued. The patient experienced marked symptomatic improvement within a week. Myopathies with neuropathies may be found with the use of colchicine. This case was unusual because of the absence of abnormal spontaneous activity and increased creatinine kinase, as typically reported with colchicine myopathy. Level of Evidence V
