The problem of nociception and pain development in radicular pain syndromes is not clarified. In the pathophysiology of pain of radicular compression caused by stenosis or disc prolapse, morphological complex nerve root/ganglion is the key structure. Chronic compression forces on the nerve structure cause structural changes. ⋯ The membrane threshold shift in nociceptive fibers is an important prerequisite for pain perception in nerve root compression. New biochemical aspects in the pathophysiology of radicular syndromes are presented, which could explain the discrepancy between pain and objective clinical findings. The article concludes that a better understanding of the nerve root pathophysiology will bring a more differentiated pain-management strategy.

Following head trauma many different forms of headache can develop. Complaints in the early post-traumatic period appear to be organic in most cases. Later in the course post-traumatic headache frequently shows a psychogenic picture. Describing the causative factors and discussing the therapeutic guidelines, the authors explain how psychological influences can form chronic pain syndromes.

Morphine and other strong opioids are very often needed for the treatment of severe pain. In the FRG the prescription of these analgesics is limited by law, especially for outpatients. Special prescriptions are needed for opioid medication. ⋯ Insufficient treatment of outpatients suffering from severe pain is obvious. The complex regulations in the FRG concerning the prescription of strong opioids are the main reason for insufficient treatment. It is necessary to liberalize these regulations in order to treat severe pain better.
