Hives, Poison Ivy, A Rash, Allergic Reaction

Call the doctors office or go the the ER.

it could be a reaction to something that he ate

He needs to figure out what kinda of allergic reaction he's got, has he been around something he doesn't usually come in contact with? did he use a weird soap that made him break out? Or it could be a heat rash of some sort.

umm is your mom home ... call the doctor and tell him the syptoms he should b able to tell you what to do from there

heat rash, allergic reaction, could be something else.
Either way, tell your mum or anyone that's there with you and go to the doctors or the walk-in centre to be on the safe side.

heat rash mabey starting of exemah cause a get that a lot at the start of it. you mabey want 2 get a cloth and put cold water on it and put it where he is itching should stop it being so itchy.

I'd call the E.R and see what they say. It could be an ellergic reaction- to meds or food. Tell them if he's gotten into anything that he hasnt ever been in to before. They might suggest he takes some benedryl. Where are your parents??
