[Myofascial pain syndrome-a neurovegetative complaints pattern]

The diagnosis of myofascial pain syndrome is usually made after structural-morphological explanations have been ruled out. The lack of positive findings to guide treatment inevitably leaves room for interpretation despite the extensive use of all imaging, neurophysiological or serological diagnostics. Under these circumstances, a careful differential diagnosis must be made between functional and structural aspects, both of which in many cases must be assessed in their different relevance. Particular attention must be paid to indications of vegetative-sympathetic adjustment disorders.The great importance of a clinical, experience-based approach to this symptom pattern becomes clear here, especially if the technical diagnostic data is of no help. The dominance of imaging findings naturally promotes a structure-based, mechanistic understanding of the illness. In contrast, the emotional, vegetative mood of the patient should be given greater consideration as a diagnostic and therapeutic focus. Treatment measures should have a high success rate, as persistent reductions in stimulus thresholds may lead to prognostically unfavorable chronification.
