Yes, in a nutshell, to your query. Fibromyalgia is a genuine disease that affects around four million Americans. It is a persistent pain syndrome that scientists believe is caused by a neural system failure. There are many things that can cause symptoms similar to those of fibromyalgia, including other medical conditions and drugs. Many people who claim they have the condition actually suffer from another disorder called chronic fatigue syndrome (CFS). Experts say that about 10% of people with CFS also have fibromyalgia. However, most people will only have one of these disorders at a time. People who fake illness to get out of work or school often use diseases like fibromyalgia to explain their inability to get off of bed or walk up stairs. They may also claim injury as an excuse for not going to school or job interviews. The sad truth is that there are people who abuse this system by making false claims about having fibromyalgia in order to avoid work responsibilities or avoid being sent home early. This may include lying about having pain in certain areas of the body or claiming to need sleep during office hours so that they can go back to work after everyone else has left for the day. It is important to note that there is no way to fake having fibromyalgia. If you are able to walk up stairs or lift objects then you cannot really complain about all your pain.
