Daughter has pain in throat and ears when swallowing

Whenever my daughter, she is 14, swallows her throat and ears hurt a lot. She does have the occasional headache. I’ve given here some paracetamol, lozenges, warm/room temp drinks and ensured that she has had plenty of sleep. Is it an infection or something, i’m not sure so any comments cheers in advance, and happy new year! :)
