Gas pain?

My son’s gas issues have returned with a vengeance. He now arches his back hard when he farts and cries. Last night it even woke him up and it’s been months since gas woke him up. Is this normal? Should I call his pediatrician? It’s been the last few days. They also smell awful. He isn’t constipated and doesn’t have the same problems pooping, just when he passes gas
