There is a significant debate whether local infiltration techniques may be a method to treat complicated chronic pain syndromes, e.g. refractory headache. Until now there is a lack of evidence regarding efficacy of this treatment especially in long term follow up. Similarly, indication and management are under debate. Aim of this trial is to analyse pain scores during first treatment with anaesthesiological infiltration series.

Patients with therapy refractory chronic pain are treated with local infiltration techniques using e.g. local anaesthetics, opioids or drug combinations. Targeted structures are e.g. Ganglion stellatum, Ganglion pterygopallatinum, Trigeminal nerve branches (V1-V3). Patients receive a context- sensitive number of blocks in a series of infiltrations depenting on their pain course.
