Under all circumstances, it is advisable to keep a record to help track and identify the source or what event sets off your symptoms. With this information in hand, you will be able to make the necessary changes to avoid future headaches. The information that should be recorded is the date and time the headache began, what you ate for the past 24 hours, how long you slept the night before, what you were doing and thinking about just before the headache started, any stress that you be under, how long the headache lasts, and what event or treatment or behavior patterns made it go away. You may soon see the formation of a pattern which will be most useful.
A headache may be relieved by resting with your eyes closed and head supported. Relaxation techniques can help. A massage or heat applied to the back of the upper neck can be effective in relieving tension headaches.
