question: I recently have seen a doctor for muscle pain in my legs and upper arms...it started about 4 months ago after tripping over a dog. Oh I am 57 and female....when I saw the doctor the second time they mentioned the possibility of a muscle virus and did more blood work and had me get a chest X-ray to rule out pneumonia...I know I don t have pneumonia. Is it possible I have developed fibromyalgia?
