Can an infused ear cause me to feel discomfort in my eye, temple and cheek? How long does an infused ear normally take to heal?

Infused ear?? I have never heard of an "infused" ear. If you mean infected, then an external infection or swimmers ear can cause significant pain in the ear and around the ear. Another possibility is that your ear is fine but your jaw joint is is badly inflamed with resulting muscle pain and spasm. Jaw muscle spasm will give you all the symptoms you describe. Try advil, (ibuprofen) soft food and ice. If no better see ent.
Please clarify. When you say infused ear, did you have a middle ear injection procedure? Could you mean a plugged or clogged/stuffy ear? Is your ear hurting or does it feel like it has a lot of pressure in it? Is your hearing muffled?
