The study sought to assess the utility of controlled diagnostic blocks in patients with probable cervicogenic headache by determining the prevalence of sources of pain among the upper and lower synovial joints of the cervical spine. ⋯ Controlled diagnostic blocks can establish the source of pain in the majority of patients presenting with probable cervicogenic headache, with C2-3 being the most common source. On the basis of pretest probability, diagnostic algorithms should commence investigations at C2-3. Second and third steps in the algorithm should differ according to whether headache is the dominant or nondominant complaint.

The purpose of our study was to perform a systematic review and meta-analysis of randomized, blinded, placebo-controlled studies that, following third-molar extraction, utilized either a combination of acetaminophen (600 mg) with codeine (60 mg) or ibuprofen (400 mg) for pain management. ⋯ Our data indicate that single dose of ibuprofen (400 mg) is an effective pain reducer for post third molar extraction pain.

Myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) and fibromyalgia (FM) are two debilitating, moderately comorbid illnesses in which chronic musculoskeletal pain symptoms are prevalent. These individuals can experience post-exertional malaise (PEM), a phenomenon in which symptom severity is worsened for 24 hours or longer after physical stress, but the pain-related component of PEM is not well characterized. ⋯ People with ME/CFS and FM experience small to moderate increases in pain severity after exercise, which confirms pain as a component of PEM and emphasizes its debilitating impact in ME/CFS and FM. Future directions include determining mechanisms of pain-related PEM and developing exercise prescriptions that minimize symptom exacerbation in these illnesses.
