The typical “extensor” patient is the one who suffers from the classic “witch’s shot”. The pain arises acutely at the lumbar and/or sciatic level with radicular or similar-radicular distribution (rarely on the front of the thigh). The picture can have dramatic aspects due to high suffering. This patient hardly ever immediately accesses a specialist referral: a decision entailing waiting times and a painful transfer from home. Often, the patient requests a home visit from their family doctor or presents in the emergency room. The anamnesis is rarely informative.
