I am a 39 yo female experiencing same issues. However, I was also found to have a heart condition, patent foramen ovale (PFO) with TIAs. I had this corrected in surgery with a closure device. Eighteen months later I have been diagnosed with complex migraine syndrome after fainting and remaining unconscious for over 30 minutes. The prescribed treatment for the migraines is Topamax, which aids in prevention, and Midrin (at onset) for the pain. Vicodin was originally prescribed for pain, but tended to exaserbate the symptoms.
Perhaps your medication is the same, if not ask your neurologist about this combo.
