Non-Fibrositic lumbar subcutaneous nodules: prevalence and clinical significance By R. L. Swezey The Arthritis and Back Pain Center, Santa Monica, California, USA British Journal of Rheumatology 1991:30:376-378 Swezey starts commenting that the fibrositis and myofascial syndromes remained obscure or ignored for many years because of the paucity of objective clinical findings. He states that the only clinically objective finding is the presence of palpable tender nodules and trigger points manifested as tender indurations in muscles. BUT there has been inability to demonstrate any laboratory, electrodiagnostic or radiographic abnormalities. Swezey states that lately there has been emphasis and interest into he soft tissue and musculoskeletal palpation and the called myofascial syndromes, also in the lumbosacral subcutaneous nodules with fibromialgia. Because of these, he thinks it is important to differentiate benign non-specific subcutaneous nodules that are located adjacent to the lumbosacral and iliac crest area next to the tender points. That’s why they made a survey to determinate the presence of the nodules in patients with low back pain and fibromialgia syndrome.
