Pain is a frequent reason for patients to see their general practitioner, and failure to provide sufficient treatment is unsatisfying for both doctor and patient. In this case report, we describe how a 51-year-old woman who had an eight-year history of pain in the neck, left arm and shoulder and had tried several types of conservative treatment, became pain free after removal of an intramuscular lipoma in m. trapezius. Intramuscular lipomas are seldom the culprit of chronic pain, but we want to remind the reader that occasionally, the answer to a complex problem can be a simple lipoma.
