CFS drs in Canada

Would you mind sharing a little about what triggered CFS for you (if you know)? I only ask because I've dealt with debilitating exhaustion during periods of my life. This was triggered by significant medical issues, but once undergoing treatment, symptoms eventually improved (though it took a long time). Sometimes doctors in the specialty of whatever triggered this fatigue can offer good advice because you won't be the first patient to complain of this symptom. I know it's frustrating, but many, many people do improve. Proper diagnosis is often the difficult part.
