I've tried to push myself thru this but only end up feeling overwhelmed by the itch, short of breath, head feels dizzy and faintish and I think I'm going to be sick. I'm no where near
my physical limits either when this happens. I've even tried just walking at a fast pace but it still happens. I've tested every scenario I can think of and have concluded that weather, clothing, temperature, creams, dry skin, laundry detergent, medication, hydration...has nothing to do with it.
