Fibromyalgia is widespread pain. Symptoms are sensations of burning, tingling, numbness, stiffness, fatigue, poor sleep, mood disorders, and bowel altercations. Fibromyalgia management is aimed at improving the quality of life but anti-inflammatory and analgesic drugs like opioids have marginal effects and are generally not tolerated. Arthritis refers to more than 100 disorders of the musculoskeletal system. Symptoms are often uncontrolled, not allowing a good quality of life. Current treatments for fibromyalgia/arthritis pain are Transcranial Magnetic Stimulation and Transcutaneous Electrical Nerve Stimulation. These treatments are used but have high bias. Low energy pulsed electromagnetic fields (PEMF) is based on the use of magnetotherapy, which produces modulatory and neuroprotective effects. PEMF also promotes osteogenesis and angiogenesis. PEMF has moderate beneficial effects in treating pain from osteoarthritis when applied to the whole body and or a specific joint. PEMF can provide a non-invasive, safe, and easy to apply method to treat pain, immflamtion, and dysfunctions associated with fibromyalgia/arthritis (RA and OA).
