My 5 yr old daughter came home early from school today complaining of a stomachache and some nausea. I figured gas or constipation. She went right to sleep when we got home. (1pm-ish, she doesn’t usually take naps at home) thought she felt warm but no fever. Take temp again after 3, reads 99.9 underarm. Stomach pain gets worse, she says it’s on lower to mid right side and thought she was going to throw up but didn’t. Crying and holding her stomach, nausea continues. Around 6 temp is up to 100.6, stomach pain is around belly button. I hear a loud gurgling sound throughout her and she’s started to burp some. Sleeps again. Wakes up at 9pm, fever is the same, pain seems to have eased unless pressing on it, but pain is on lower to mid right side. Felt side of throat/neck and she responds in pain. Inside of throat is not red or swollen and she hasn’t complained of that area until I touched it. What is this???
