It is common in ppl with fibro I have found. I have it also and it is just another thing to add to the list of fibro issues so you are sure not alone. If you type in costo or costa in the site search box you are sure to find plenty of posts with others that have it. I know when it is bothering me I need to stay as calm as possible because stress can bring it on or make it worse. It helps me to use heat when I am having a flare up of it.
