Should I take him to the doctor?

My lo is 10mo. Yesterday late morning is when it started he pooped almost every diaper. They was maybe one or two where he didn’t poop. And he just pooped again this morning. And is butt is super red like his entire butt and it hurts him when I try to wipe. I’ve been putting diaper cream all over and he’s okay after that. And last night before bed he was fine then he just freaked out and screamed and cried for like a half hour idk why and it took my boyfriend another half hour or so to get him to bed. After that he slept all night. He doesn’t have a fever, he has puked, he’s being active as normal. I haven’t gave him anything different so I don’t know what the deal is.
