Hi, may I answer your health queries right now ? Please type your query here...My son is 5 yrs old. Since Xmas time he has been experiencing fever that comes and goes. His energy levels have decreased. He is normally a very good eater and he has not much of an appetite. He has dropped 7 lbs in the last month. He seems to keep catching coughs and colds from the kids at school, which normally does not affect him so much. He is very pale and seems to be very tired and weak in comparison to usual. He is VERY busy normally. He has up until lately been a very healthy little boy. I have taken him in a couple of times and have been told fever of unknown origin and bad luck catching viruses one after another. Help please.
