||A 32-year-old man comes in regularly because his back hurts. You suspect malingering because he continually requests narcotic pain relievers and imaging studies of his spine. He has come 5 times in the last 6 months with the same problem, typically stating that the pain improves with exercise and leaning forward but is worse at night; pain also occurs at times in his buttocks and does not improve with rest. On physical examination you find no abnormalities of the spine besides inflexibility of the lower spine when he leans forward. Neurological examination is normal, including the absence of pain on a straight-leg raise test. X-ray of the spine and sacroiliac joint is normal. All blood tests including rheumatoid factor, ESR, and C-reactive protein are normal. Today, he again claims to have only minimal improvement with ibuprofen. He is requesting narcotics and a “doctor’s note to get out of work.” What is the next best step in management?
A. MRI of the sacroiliac joint
B. Anti-cyclic citrullinated peptide (anti-CCP)
C. HLA-B27 testing
E. Report to employer for malingering
