Ear infection maybe?

My 3 month old had been having a little bit of a cough and sunny ish nose and he just started crying really bad whenever he turned his head and lays on his ears or when I'm breastfeeding him and his ears touch my arm, should I be worried about an ear infection? Do I take him in to a kid's urgent care? He has lip repair or Feb 9 and he can't be any type of sick by then otherwise they'll pospone his surgery.. please help! Suggestions??
