Polymyalgia rheumatica will have an elevated ESR and possibly other elevated lab values (i.e. CRP, CPK).

Fibromyalgia, by definition, has no change in lab values.

Also, question stems mentioning fibromyalgia will usually make it a point to mention that there is localized tenderness in several different points throughout the body. Polymyalgia rheumatica, by contrast, is usually localized to the proximal muscles.

Also to add, Polymyalgia Rheumatica is associated with Giant Cell arteritis in 15 % of patients, so also look for scalp tenderness along with elevated ESR to help you differentiate between the 2

Fibromyalgia is a medical disorder characterized by chronic widespread pain and allodynia, a heightened and painful response to pressure.
Quote:
Multicenter Criteria Committee of the American College of Rheumatology. These criteria, which are known informally as "the ACR 1990", define fibromyalgia according to the presence of the following criteria:
A history of widespread pain lasting more than three months—affecting all four quadrants of the body, i.e., both sides, and above and below the waist.
Tender points—there are 18 designated possible tender points (although a person with the disorder may feel pain in other areas as well). The patient must feel pain at 11 or more of these points for fibromyalgia to be considered.
Polymyalgia rheumatica is a syndrome with pain and stiffness, usually in the neck, shoulders, and hips.
Most PMR sufferers wake up in the morning with pain in their muscles;
Limitation in shoulder motion, or swelling of the joints in the wrists or hands.
Quote:
The pain and stiffness result from the activity of inflammatory cells and proteins that are normally a part of the body's disease-fighting immune system, and the inflammatory activity seems to be concentrated in tissues surrounding the affected joints.[6] During this disorder, the white blood cells in the body attack the lining of the joints, causing inflammation.

Think of Polymyalgia Rheumatica as muscular version Rheumatoid arthritis.
Patients with Rheumatoid arthritis wakes up with pain and stiffness of joints and patients with Polymyalgia Rheumatica wakes up with pain and stiffness in their muscles.
