Over the past few weeks, I've noticed some on-going pain in my left eye, and left temple. My eye feels sore, with a kind of dull, nagging pain, and feels full/under pressure. My temple is sore, and hurts like hell when I poke it (I know, I know, don't poke it, then...) And I know I'm a night clencher, so I'm wondering if this is most likely the problem, or if I have something else going on and should be more worried?
