1yo wakes up crying and won’t settle

It’s not unusual for my 13 month old to wake up not even an hour after falling to sleep, he is either rocked back to sleep or fed. Just recently he has been waking up crying and won’t settle, refused to be breastfed and nothing else soothes him. What can this be? I have tried EVERYTHING! We have resorted to sticking the TV on for him to fall asleep to, but we don’t want to create a relationship with the tv and falling to sleep!
