I did a two day CPT in Ithaca, crashed afterwards, and never recovered to a pre-test level. To be explicit, at the time I was only moderately ill, and there were other stressors involved, including a two day car trip as a passenger. Each intense stressor I have encountered since has followed the same pattern of a crash followed by some recovery, but not to pre-stressor level. I am now severe, not quite bed bound. Personally I would be very cautious, but as we know there's great variation in this disease and it may affect you differently. Best of luck!
PS- There is a version of stress test that uses drugs instead of exercise to induce stress. Not sure if that might be a better choice, but you may want to explore that option further.
Has anyone done a treadmill stress test? Did you crash afterwards? I need eye surgery but my cardiologist wants me to do a stress test first.
