Last year when ds2 got his vaccines his arm swelled up and turned purple and red. His skin got scaly and hot to the touch and hard as a rock. There was yellow pus coming out where he got the shots. His arm was hurting him a lot and he said he couldn't feel his hand.
This year he tells me he cannot lift his arm. I check his arm and sure enough it is hot and hard to the touch less than four hours later. I put a cold compress on it and will monitor it but I hate this. His arm hurts and is just hanging there limply to the side wile he uses his other hand for everything.
