Ear Ache And Hurts To Chew What Is The Cause Of This Ear Ache?

What is the cause of this ear ache? - ear ache and hurts to chew

I think I should explain, first, said these days I've had allergies. Blinding headaches, cough, sore throat, etc. However, today I had my head on the door. No big deal, I so badly. Already it begins to really disturbs me ... It feels like a shock when you touch me, and I had an ear ache hurts when I chew, or superficial. Is this ear pain also hurts an allergy or as a result of the head? And there's nothing I can do to help?
