Tests that may be needed
While there is no lab test to confirm a diagnosis of fibromyalgia, your doctor may want to rule out other conditions that may have similar symptoms. Blood tests may include:
- Complete blood count
- Erythrocyte sedimentation rate
- Thyroid function tests
- Vitamin D levels
Your doctor may also perform a careful physical exam of your muscles and joints, as well as a neurological exam to look for other causes of your symptoms. If there’s a chance that you may be suffering from sleep apnea, your doctor may recommend a sleep study.
More clues for fibromyalgia diagnosis
People who have fibromyalgia also often wake up tired, even after they’ve slept continuously for more than eight hours. Brief periods of physical or mental exertion may leave them exhausted. They may also have problems with short-term memory and the ability to concentrate. If you have these problems, your doctor may ask you to rank how severely they affect your day-to-day activities.
Fibromyalgia often coexists with other health problems, so your doctor may also ask if you experience:
- Irritable bowel syndrome
- Jaw pain
- Anxiety or depression
- Frequent or painful urination
