This has been a bad week. My son has had tantrums every day since Tuesday. It seems to come on all of a sudden. He is fine all day, we eat dinner, clean up, watch tv or a movie and then boom - he starts getting very angry and upset. He says he doesn't know why he is so angry. He said he feels fine one minute, and the next he feels anger coming on. He is also complaining about bad leg pains. He was screaming out from the pain last night. He actually came home from school today because of his leg pains. I am taking him to his pediatrician today and hopefully and he will give me some answers or help. I need to find out also if the steroid medications that my son has been on for the last couple of months (given to him when he had pneumonia and is continuing to take for asthma) is any reason for this change in him.
