This week’s case features Greg, a 42-year-old male patient, who while lifting a box at work developed sudden lumbar back pain, which is non-radiating but debilitating. The patient was seen in the ER, where he was diagnosed with a back strain, and provided with prescriptions for cyclobenzaprine and lidocaine patches. In addition, the patient has been using over-the-counter NSAIDS and Acetaminophen – with mild relief. He sees you in clinic, concerned about his continued pain and asking what else can be done. On exam, the patient has areas that are exquisitely TTP at his left SI joint and left perilumbar region around L4-5. This is the perfect patient to possibly receive in office trigger point injections, an effective and safe intervention – and the subject of today’s microlearning.
