My weird "PEM"?

    I was hoping to get some insight into what happens to me after exercise.

    I have no problem exercising, and am fine during and right after. I have mild POTS but manage to exercise through it no problem.

    Exactly 12 hours later I get lightheaded for about 4-5 hours and then it goes away. My body is absolutely fine though. I've been watching it for weeks, and it's like clockwork in terms of timing and duration, regerdless of exercise intensity.

    What could this be?

    I've been trying to guess myself:

    -cortisol crash?
    -mast cell degranulation? But I don't get any allergic type symptoms, just lightheaded.
    -Is this my own special version of PEM? It can't just last for 4-5 hours, and it should be more than lightheadedness...

    I'm at a loss.

    Thanks,

    Maybe an immune system shift via cytokine levels changing? Maybe adrenal hormone levels drop?
