Many lists of chronic fatigue syndrome symptoms only contain a few symptoms, such as fatigue, muscle pain and exercise intolerance. However, this condition involves a lot more potential symptoms that can impact just about any part of the body.
Knowing all of the possible symptoms can help you in a few different ways:
- It can help your doctor diagnose you properly;
- Tracking them can help you identify symptom triggers;
- It can help you see that you're not the only one experiencing these problems.
Some of the items in the list are noted as overlapping conditions, which means they're common enough to be considered symptomatic but are actually separate conditions that need to be diagnosed and treated in their own right.
Some people with this illness have symptoms that come and go and to vary greatly in severity from day to day or week to week. Others may have constant symptoms with very little change over time.
