My first thought reading your post is that he may not be having a reaction to the shots at all...strep, flu, and a stomach bug have all been causing chaos in my area and in many cases kids are coming down with more than one thing at a time...your son sounds like my kids last week. But, even if it is a reaction to the shots it sounds like you are doing the right thing and either way, calling the doctor always makes me feel like I am handling the situation the way I need to. Hope he feels better!
