Von Frey monofilaments (VFM) and Electronic von Frey are used as quantitative sensory testing to explore mechanical hyperalgesia. The aim of the study was to determine VFM and Electronic von Frey reproducibility and the time required for testing undamaged areas in volunteers and surgical in-hospital patients. ⋯ Exploration of mechanical allodynia in postoperative patients requires rapid and reliable quantitative sensory testing. Electronic von Frey was more reliable and rapid than VFM in exploring mechanical pain thresholds in undamaged areas in volunteers and patients. Further studies are required to confirm whether these results can be extrapolated to areas affected by surgery.

Venous blood sampling is one of the most common diagnostic medical procedures performed in clinical practice. It has been shown that negatively loaded words may result in negative affective reactions and, consequently, in an increased perception of pain. We aimed to evaluate whether common warnings before venous blood sampling might induce unnecessary pain. ⋯ Words associated with pain increase the perception of pain during venous blood sampling. Omitting these words may be a simple and essential method by which to avoid unnecessary pain.

Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) syndrome is a rare type of trigeminal autonomic cephalalgia. SUNCT syndrome is typically idiopathic, and secondary SUNCT syndrome after indirect injury is very rare. We report a case of SUNCT syndrome manifested dramatically after a whiplash injury and treated by greater occipital nerve (GON) block. ⋯ Secondary SUNCT syndrome induced by whiplash injury is rare. Our case showed good outcome of SUNCT syndrome treated by GON.
