16 month old inconsolable

My 16 month old woke up an hour and a half ago absolutely beside himself. He wakes frequently but he is never this upset or hard to get down… no temp and he’s had teething granules but he’s screaming on and off. I even put the TV in which I never do and it only distracted him for 30 seconds. I think it could possibly be constipation but I am so panicky. Does anyone have any advice?
