Dr. Not enough info. in your answer. You state many could be this etc. I will just call the hospital. What A (sight for sore eyes) Thanks Doc.
Some possibilities include sinusitis, trigeminal neuralgia, cluster headaches, migraine headaches, hypertension, increased intracranial pressure, temporal arteritis, glaucoma and others. I would first see an ophthalmologist and then consider a neurologist if necessary.
