If you have been seeing your primary care or specialist doctor
regularly through this process, and the tests are all coming back negative, then that is very encouraging, because it means that there is probably not a serious underlying undiscovered medical process at work.
I would suggest taking a step back and working with your doctors to see if all of these symptoms might be in some way related to your fibromyalgia and mood symptoms. People who have a diagnosis of fibromyalgia often a disturbance in the way their bodies process pain signals, which can lead to a lot of diffuse pain symptoms. These pain symptoms that are chronic and unrelieved can in turn trigger a deterioration of mood symptoms, which then worsen the pain symptoms, and so on. Breaking out of this cycle usually requires a multidisciplinary team, which can include a fibromyalgia or pain specialist
as well as a psychiatrist
. In addition, complementary therapies, such as exercise, meditation, and the like are also very helpful.
I would start by seeing if you can discuss the whole complex of your symptoms the doctor who knows you best and who is treating your fibromyalgia, to see if this idea makes sense.
