Common Overlapping Conditions

Common Overlapping Conditions

Fibromyalgia Sufferers Often Have Other Chronic Conditions

There are other conditions that have symptoms which are similar to those of fibromyalgia.

These conditions can often occur together with fibromyalgia. That’s why it’s important to understand that a diagnosis of other conditions does not rule out a fibromyalgia diagnosis. (And, in turn, a diagnosis of fibromyalgia does not rule out other conditions.)

The presence of these overlapping conditions (called comorbidities) can “muddy the waters.” This is yet another reason so many fibromyalgia sufferers struggle to get a diagnosis.

The following chart shows some of the conditions that often co-exist with fibromyalgia. It also shows how often they are reported to occur. Your doctor may want to check for these co-existing conditions in addition to fibromyalgia.
