Hi, FibroWolf, and welcome! I'm so glad you found us and joined in. You already see how wonderful our members and and how helpful they are, too. I think you will like it here.
Usually doctors run you through a myriad of tests to rule out other illnesses. There is no specific test for fibro except the tender point test. The symptoms of fibro are like that of other illnesses so those illnesses need to be ruled out before they know for sure it's fibro they are dealing with.
Be sure to read Fibro 101...the second thread on the forum. There is a link called What Else Could It Be and you will see what needs to be ruled out. Other good starting links would be Symptoms and A Thorough Explanation of Fibromyalgia. You might see yourself there.
I'm looking forward to getting to know you better. Don't hesitate to ask questions because we are here to help you. Hope to hear more from you soon.
