See neurologist: Your unpleasant symptoms have a wide number of possible causes. The best way to deal with this is to see a neurologist and XRays or other imaging studies may be necessary.

Be seen: If these are new symptoms, you should be seen promptly. THe combination could be a variety of things, and you need a good history and examination to ferret this out.

Need to be seen: right away, either go to the ER or to your ophthalmologist, you can't wait on these symptoms, good luck
