There is no connection to the two prolems that you are having. Migraines are causes by many things such as, Dislocated and / or Pinched nerves in your upper Back, Neck and Shoulder Areas, High Blood Pressure, Disfunctioning of some of your ogans, High Stress, etc. Your low back pain may be caused by pinched and / or dislocated nerves(sciatic) which run down from your lower back to under your feet. If you got your doctor's view about your problem, I would suggest you visit a very good massage therapist and view my Web Site at: " http://ca.geocities.com/painlessjoe/ " for help relieving your migraines and your low back pain.
