Migraine Triggers Experts have identified many triggers that may set off attacks. Tracking your migraines in writing is a must, so that you can predict and even prevent attacks.
Whenever one strikes, note the date, time it began and ends, intensity, symptoms, plus foods you have eaten, stress level and anything else you suspect may have triggered it. Women should also note where they are in their monthly cycle. List any medications you take or other strategies you try, and the results. A detailed diary will help you make the necessary changes to prevent migraines.

situation. Stress reducing techniques, such as biofeedback or relaxation therapy, are very useful for prevention. Sleep: A late night or any change in your sleep patterns could also provoke an attack, as can skipping a meal or fasting.. |
