In addition to the influence of tissue damage, the intensity of pain is also related to individual cognitive factors. The Pain Catastrophizing Scale (PCS) is used to measure individual tendency toward pain by inquiring about a subject's cognitive characteristics. Building on the knowledge that the venipuncture process causes severe pain and anxiety in some patients, the objective of this study was to investigate the relationship between the PCS score and venipuncture pain. ⋯ There was a positive correlation between venipuncture pain and PCS score. Consequently, the venipuncture pain score could be useful in informing practitioners about a patient's pain considerations.

Transforaminal epidural steroid injections (TFESI) are commonly performed for the treatment of lumbar herniated nucleus pulposus and lumbosacral radiculopathy. Although rare, documented complications including spinal cord infarction, paraparesis, epidural abscess, paraplegia, and epidural hematoma have been reported. Here, we present a case of perineural hematoma affecting the L4 nerve root resulting in progressive acute-on-chronic lumbar radiculopathy following TFESI. ⋯ Although extremely rare, perineural or foraminal hematomas may occur as a serious complication of TFESI, even in the setting of a standardized procedure. Hematoma may cause worsening of symptoms in the acute and subacute phase following TFESI. Further investigation into the etiologies of such injuries is warranted and must be added to the considerations of pain physicians performing these procedures.

Transforaminal epidural steroid injections (TFESIs) are often used to treat lumbar foraminal stenosis. Injectate pressure (of contrast) was monitored during fluoroscopically guided TFESI to assess the effect on short-term pain reduction. ⋯ In this setting, relative injectate pressures had no significant effect on immediate outcomes of TFESI.
