As far as a relationship between fibromyalgia and Hashimoto's, about all I can find is this;
"People with rheumatoid arthritis and other autoimmune diseases are particularly likely to develop fibromyalgia."
and this;
"If you have a rheumatic disease, such as rheumatoid arthritis, lupus or ankylosing spondylitis, you may be more likely to have fibromyalgia. "
and this;
"Like other rheumatic diseases, fibromyalgia could be the result of a genetic tendency that's passed from mother to daughter. Some researchers believe that a person's genes may regulate the way his or her body processes painful stimuli. These scientists theorize that people with fibromyalgia may have a gene or genes that cause them to react intensely to stimuli that most people would not perceive as painful. To date, these genes have not been isolated or identified.
It's thought that when a person with this genetic tendency is exposed to certain emotional or physical stressors -- such as a traumatic crisis or a serious illness -- there is a change in the body's response to stress. This change can result in a higher sensitivity of the entire body to pain."
"While researchers have identified some common risk factors for fibromyalgia, there are still many people with the disease who have none of these traits. Also, some women have fibromyalgia with certain diseases, such as osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus (SLE), or other autoimmune diseases. But others have fibromyalgia without any underlying disease."
They hint that it is autoimmune in nature and surmise there is a genetic predisposition. They think a serious illness may trigger it, but then they say people with none of these conditions or criteria can also have it.
Very confusing. I never saw the word Hashimoto's mentioned. But "other autoimmune coditions" gets mentioned a lot. However, there is absolutely no laboratory test to detect, confirm, or rule out it's presence.
It's just a big question mark.
