<s>[INST] Ive had a headache for almost 2 months now. Its only on the right side of my head and the worst pain is in my temple, ear and jaw. The right side of my face is swollen severely and my temple is bruised. When the pain shoots through my head into my ear and into my jaw it makes me clench my teeth really hard because it hurts so bad. What is causing this and how can I stop it?

You may consult your family doctor or dentist and if required, he will refer you to other specialists for further investigation and treatment. Hope this helps you. Wishing you good health...
