question: Hello! I am an 17 year old athlete. I have a fever for atleast 1 week. I rested for 3 days. the following day i went back in our training. Then suddenly I easily get tired and became weak easily. Isn t all the hardwork was gone? Can you please help me to get back with strength and conditioning? or do i need to rest more days to recover? I hope you ll reply to this simple question.
