Fever tonight

M felt bad all day - saying "ow" everytime we moved him, wanting to lie back down in his bed instead of playing, no walking. I kept telling everyone that he was worse than he was yesterday. At about 7 pm he said he wanted to go to bed - turned around right in the middle of his car ride/date with a pretty little toddler here visiting her infant brother and made snoring sounds while he pointed down the hall to our room. As soon as we laid him down he shivered and told me he was cold. His hands and feet were icy. His head was hot. He had a fever and kept pointing to his diaper all day saying ow. He's had blood and fluids tested now for different things so we should know soon what is going on. Hopefully it is an easy fix. I admit I am freaking out right now. 6 days post heart surgery + unexplained fever and pain = mama losing her mind with worry
