Q: I have had migraines without aura for over 40 years. However, nothing works for headaches caused by high barometric pressure. I have been on Imitrex® for years, and it generally works, but I have to take it again when the headache comes back after it rains or when there are unstable weather patterns. I know to be careful not to take too many analgesics or Imitrex, so rebound is not a problem. I am also careful of what I eat and, after so many years, I know my triggers. My grandmother, mother and brother had these headaches and I passed them on to my two daughters. What can I do about these high pressure headaches?
A: Headaches triggered by barometric pressure are a challenge for many headache sufferers. Studies have shown that some headaches are triggered by relative humidity, barometric pressure, temperature and precipitation. It’s possible that the change in weather pattern, not the specific weather itself, is the triggering factor. You mention a strong family predisposition to migraine. That inherited sensitive nervous system is likely responding to changes in weather.
Unfortunately, there is no single simple solution for this trigger. The best thing you can do is raise your protective level by eating a healthy diet, avoiding caffeine, having good sleep habits, exercising regularly and managing stress. Preventive medications may also be necessary to reduce your risk of headaches, including those triggered by weather changes. Your healthcare professional can work with you to find the best medication or combination of medications to reduce your headache frequency. When you do get a migraine, whether or not it’s from the weather, treat it early to get pain-free.
