I have a 5 yr old son he was diagnosed with a innocent heart murmur and I was told that it would only act up when he gets sick that I have nothing to worry about. He also has asthma and seasonal allergies but that s it....but recently he has half the energy he use to have no appitie (unless its sugarery) stomach problems (going to the bathroom a lot) and complains about his head hurting so I m really concerend and have asked his pediatrician about these symptoms but they just blow it off....the only thing that sticks out in my mind besides the heart mumor is that for thepast 4 plus months is that he has a very enlarged gland on the left side of his neck that just won t go way....please if anyone has any ideas let me know asap!
