Hi, my son is 4 1/2. He has had reoccurring fevers for 4 months. They get as high as 105. It s almost like his body crashes for about a week, and then he is fine for about a month until it happens again.Along with his fever, he has lower leg and feet pain, and eyes are really sensitive to everything. He says they hurt. No other symptoms. I m desperate for answers. Thank you, Heather We have seen several doctors and they can t seem to tell us whats going on with our little boy. When i was little i had a mutation of my genes .
