Hi, again, Quiltermama! I'm glad to see you started an introductory thread. You are getting to meet some of our great members!
Yes, you do have to rule out other illnesses before a diagnosis of fibro is given. So many of our symptoms fit other illnesses...illnesses that have tests to see if you have it. Fibro doesn't have any tests so you have to rule the others out first.
Be sure to read Fibro 101...the first thread on the forum. There are links to good info about fibro and you will learn a lot there. Good strarting links would be the ones called Symptoms, What Else Could It Be, and A Thorough Explanation of Fibromyalgia. You just might see yourself there.
Don't hesitate to ask questions because we are here to help you. I hope to hear more from you soon.
