7 month old starting to wake up crying through the night!

My little boy has always been a reasonably ok sleeper, going from 7-4am having a feed then back to sleep till 8am. The last 2 weeks he is waking numerous times in the night screaming and wanting either a drink of water or a cuddle to go back to sleep. We figured it was teething but surely if it was teething he wouldnt go straight back to sleep off a cuddle as he would still be in pain regardless? not sure what else to do!!
