I did crash for a few days but came out of it but we each respond differently
so true. my test was on Dec 4th. went from activity level of 3-4 hours out of bed daily (on a good day) to 1-2 hours out of bed daily after this test.
this test was wwaayyy too much for my body to handle. they told me to stay on the treadmill "as long as I could" not as long as I felt was safe for me.
*i have POTS and i had a weird sudden spike in my heart rate one day while sweeping the floor (HR jumped to 198 on fitbit) and i almost passed out
as a result, did a 3 week heart monitor and echo. cardio stated everything looked ok structurally w heart (he thinks possible SVT caused HR spike) but just to "be safe" i should have an exercise stress test .
i told him how concerned i was about the test and fear of a bad crash afterwords. he stated that not to worry, it should only take a few days of feeling tired afterwards, then i would be fine. well, nearly 3 months later, i still have not recovered from this test.
in my case, my ME/CFS has consistently gotten worse over the years, each time I have a "bad crash" my "new" baseline is always worse. only time will tell if this a permanent worsening from this test.
from reading your "new member introductory post", it sounds like you are currently not doing well. I think you are teetering on a very fragile state where it would not take much to tip you into a very severe state
I think you are being very wise by researching this first and asking a lot of questions so you can make the decision that is best for you
