Fibromyalgia with high Esr.

Hi doctor, My wife has been diagnosed for Fibromyalgia and has Esr as 40. Her symptoms are: getting pain in forearms including wrist/palm, and in lower leg, with any kind of activity.pain in feet is most severe where she gets swelling in only one feet,and unable to walk without getting much pain in feet.also gets knots in calf muscles of same leg,not in other one.but pain in hands are in both.has developed getting her stomach upset or indigestion more easily/frequently. With these symptoms,could you please suggest if these are good enough symptoms to relate to Fibromyalgia? All these Pain becomes more in evening/night, but feet one pains more in morning when she gets up and tries to walk. She doesn't feel depressed,no mood swings,doesn't have sleep issue or tiredness. Thanks
