My 7 year old male received a steroid shot on Tuesday for asthma (first time) 3-4 days later he has been doing this cough/sneeze thing and acting "off" he is still eating, drinking, going to the bathroom, and will half play with a string if you give him one but he's a lot more subdued. Is all this normal?? I'm mostly concerned about this cough/sneeze thing he is doing
