Factors that affect the number of tender points in fibromyalgia and chronic widespread pain patients who did not meet the ACR 1990 criteria for fibromyalgia: are tender points a reflection of neuropathic pain?
This study aims to compare fibromyalgia (FM) and chronic widespread pain (CWP) patients who do not fulfill the criteria for tender points (TP). ⋯ CWP patients have symptoms similar to FM patients, though less severe. The most important factor that affects the criteria for fulfilling the number TP in CWP patients is the neuropathic pain score, which suggests that FM is primarily a neuropathic pain syndrome.
