Inclusion criteria
Inclusion criteria: Patients that fall into one of the following classes: A. Neuralgia paraesthetica patients for whom the indication of a blockade of the nervus cutaneus femoris lateralis has been made. B. Patients experiencing pain in the groin area, for whom the indication of a blockade of the nervus ilioinguinalis, nervus iliohypogastricus, or nervus genitofemoralis, nervus femoralis, nervus ischiadicus, nervus peroneus, nervus tibialis anterior, nervus saphenus, nervus suralis, nervus pudendus and has been made. C. Patients experiencing pain in the arm and neck area, for whom the indication of a blockade of the nervus auricularis magnus and plexus brachialis (nn radialis, ulnaris, medianus) has been made. D. Patients experiencing discogenic lower back pain, which have been indicated for a blockade of the communicating ramus. E. Patients who have been indicated for a sympathetic blockade either because of a complex regional pain syndrome, or because of a peripheral vascular disease.

| The primary objective of the trial is to explore differences in the optical signals obtained in tissues encountered along the needle trajectory during image-guided interventional pain procedures. Therefore, successful acquisition of optical spectra at well-defined points during the image-guided interventional pain procedures is the primary study parameter. The primary objective of the trial is to explore differences in the optical signals obtained in tissues encountered along the needle trajectory during image-guided interventional pain procedures. Therefore, the primary study parameters are: 1. Successfully acquired diffuse reflectance spectra obtained in subcutaneous fat, muscle, fascia, and the adipose tissue surrounding the target nerve. 2. Confirmation images by ultrasound, fluoroscopy, and the electrical stimulation threshold levels obtained at the locations where the diffuse reflectance spectra have been collected 3. the *certainty score* on a 3-point scale provided by the physician for assignment of the type of tissue present at the needle tip, based on the information available from imaging and/or electrical stimulation | — |
