Verity92, has your Neurologist performed an MRA (which occurs inside of an MRI)? You'll want to rule out an aneurysm as the cause of this pain (this is how I found out I have one, which is one of the reasons why I have 24/7 migraines). I am currently on Topamax 50 mg 2x daily, which helps some, but side effects are aweful. I want to go on Cymbalta instead. My vision suffers and headaches/stabbing pains are still terrible. I am really sorry you are going through this. One thing for certain, if your doctor is not addressing your problems, particularly pain relief, move on until you find someone who will as this health issue will (WILL!) escalate quickly if insomnia sets in. Don't feel guilty as this is your health, you owe it to yourself, ok?
