Headaches

Since Sunday I have been experiencing these weird headaches. I am getting a sharp pain either behind my eyes or in the back of my head and it feels like an ice pick is being shoved through to my eyeballs (graphic right?). If I move my eyes in any direction, my right eye is really feeling a strain like a muscle pull, but severely intense. I have read about Optic Neuritis which is an MS problem some people experience and I do not know if this is what I have now or just some random pains. I go see the neuro next Wednesday and hopefully will know more about this before then.....I left a message today and have not heard back yet.
