I have had pain under bone of my right eyebrow for months..hurts when I press under brow bone and even when I don't it feels like a deep ache or a strained muscle. Optometrist examined eye and all seems fine. I thought it might be sinus related but I have no other so us symptoms. Pain causes me to have headache and nausea and has gone on for quite some time. Do you think I should see an ENT or a neurologist?
