Many say that the delayed post exertional symptoms start anywhere from 24-48 hrs after exertion. I myself thou find that they often start 16-18 hrs after exertion from my base line state (that is if I get delayed symptoms). So thought a survey would be good. Im also wondering if the worst the ME, if this symptom delayed response happens sooner? Note.. I've made this poll a public one so your name will show where you voted.. ive done this in the hopes I can work out if the worst the ME, the sooner the delayed symptoms may come in... a myth or fact?
