Tremors are a possible side-effect of antipsychotic drugs, called neuroleptics, sometimes prescribed to treat fibromyalgia, according to NHS Wales. Hand tremors are not among the typical symptoms of fibromyalgia, as listed by the University of Maryland Medical Center. The Fibromyalgia Support Network does mention hand tremors among the less common symptoms of fibromyalgia.
Fibromyalgia is notorious for being difficult to diagnose and having a wide range of symptoms, many of which only a minority of sufferers may experience. The defining characteristic is constant pain that is present in all four quadrants of the body and concentrated in sensitive tender points, but other possible symptoms include fatigue and sleep disturbances, digestive and urinary problems, headaches, dizziness and difficulties maintaining concentration, according to University of Maryland Medical Center. Restless legs, stiffness in muscles, and a feeling of numbness in hands and feet are other possible symptoms. As of 2015, the causes of fibromyalgia are not well understood; there is no generally accepted effective treatment, only a variety of treatments for the various symptoms.
The Fibromyalgia Support Network cautions sufferers to not automatically assume that every health problem is another symptom of fibromyalgia. Instead, patients should talk with a physician about any new symptoms that appear, as they may indicate the presence of another illness.
