This is in the lesson examples:

Sophie a mal à l'oreille.Sophie's ear aches. 
Sophie has an earache

But when I entered « Aurélie a mal à l’oreille » as the quiz answer it said I was wrong and should have answered « Aurélie a mal aux oreilles ». Which version is actually correct?

Is it ever correct to say ‘J’ai mal au tête.’ ?

Hi If: Il a mal au genou is his knee hurts. Then how do you write He hurt his knee?

My understanding is that J'ai mal à + noun is physical pain whereas Je suis malade is more like "I am sick" (perhaps with a flu or cold). Can you please confirm whether that is correct? 

As well, it would probably be useful to either link to a lesson that explains être malade or have another section in this lesson that explains the difference for future students!

What is the difference between mal and blesse?

Salut a tous

If aux dents is plural how can it be translated as I have a toothache?

Merci
