Overview: What is Fibromyalgia (FMS)?

Fibromyalgia KaleidoscopeFibromyalgia (FMS) causes chronic pain, fatigue, disturbed sleep and a myriad of other symptoms. It can occur by itself or along with other forms of arthritis, including scleroderma. Although it is never fatal, it is usually difficult to manage and can cause significant disability and disruption of quality of life.

What is Fibromyalgia? Fibromyalgia is a long-term (chronic) condition that causes widespread pain in the muscles, tendons and ligaments. Arthritis Research UK. (Also see Autoimmune Diseases)


Vitamin D status in rheumatoid arthritis (RA) patients: relation to clinical manifestations, disease activity, quality of life (QoL) and fibromyalgia syndrome (FMS). Special attention is required regarding vitamin D levels in RA patients with FMS and decreased QoL. Vitamin D should be corrected and supplementation considered among the RA management armamentarium. PubMed, Int J Rheum Dis, 2014 Oct 7. (Also see Rheumatoid Arthritis Treatments and Vitamin D Deficiency)

Sympathetic nervous system dysfunction in fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome, and interstitial cystitis. Sympathetic dysfunction could be the common underlying pathogenesis that brings on these overlapping clinical features. PubMed, J Clin Rheumatol, 2014 Apr;20(3):146-50. (Also see Chronic Fatigue Syndrome, Irritable Bowel Syndrome and Interstitial Cystitis)

Weather Conditions Do Not Affect Fibromyalgia Pain or Fatigue. Dutch researchers report that weather conditions including temperature, sunshine, and precipitation have no impact on fibromyalgia symptoms in female patients. Arthritis Care and Research, June 04 2013.


Fibromyalgia symptoms or not? Understand the fibromyalgia diagnosis process. Fibromyalgia symptoms include widespread body pain, fatigue, poor sleep and mood problems. And because fibromyalgia symptoms can occur alone or along with other diseases, it can take time to tease out which symptom is caused by what problem. Mayo Clinic.

Is it necessary to strictly diagnose fibromyalgia syndrome (FMS) in patients with chronic widespread pain (CWP)? Future research should be directed toward classification of CWP to provide guidance to clinicians in selecting effective therapies. PubMed, Clin Rheumatol, 05/26/2015.

Impaired lung transfer factor (DLCO) in fibromyalgia (FM) syndrome. FM impairs DLCO mainly as a result of a reduction in vital capacity (Vc), and that this defect is inversely proportional to the severity of the dysfunction suggesting a relationship between impaired DLCO and autonomic nerve dysfunction.

Findings suggest that the Ankylosing Spondylitis Disease Activity Score ( ASDAS) is better than the Bath Ankylosing Spondylitis Activity Disease Activity Index (BASDAI) in distinguishing patients with disease activity and the use of ASDAS may be very useful in clinical practice as it allows treating patients with the most appropriate therapy. PubMed, Rheumatol Int, 2014 Feb 8.

Autoimmune Thyroid Disease and Fibromyalgia

Fibromyalgia and chronic widespread pain in autoimmune thyroid disease.
