Toddler problems


Hi. We have 3yo girl. Today after bath she started screaming that she has pain and niddles in her butt. She was crying so much, i started crying too. Than she fell asleep, but woke up in 20m and she doesn't want to sleep. She is not crying now, but still says, she has niddle there. I will take her to pediatrician in the morning, but i am so scared, freaking out. What can this be.
