I wanted to make a thread on this and see if anyone else can relate to me. I don't get the typical PEM symptoms most people talk about. When exercising I notice negative side effects immediately. My body becomes very cold and I break out in a cold sweat, nausea, skin becomes clammy, dizziness, hearing loss, and begin to feel pretty terrible for about 30 minutes. After I stop working out however, these all go away. I don't notice any symptoms that become worse hours/days after exercising like most describe with PEM. Any idea as to what this may be?
