Both polymyalgia and fibromyalgia are both pain conditions. General practitioners who are unfamiliar with the conditions may have trouble distinguishing one from the other.
With polymyalgia, you experience stiffness in the neck, shoulders, arms and hips, particularly after you have rested for a while.
Similarly, fibromyalgia also lead to stiffness in the same parts of the body, accompanied by muscle pain. However, these are not its only symptoms. Fibromyalgia patients suffer from painful tender points which are specific to fibromyalgia. They also experience difficulty with sleeping, tiredness and mental fuzziness.
