Your headache is probably a migraine if it is severe, is on one side of the head, and is accompanied by nausea, vomiting, and sensitivity to light and noise. Your daily activities may be inhibited and you may have difficulty performing certain physical activities such as climbing stairs. Also, some people experience a migraine aura — visual disturbances or tingling sensations about an hour before the headache starts.
The best way of preventing future headaches or migraines is by avoiding individual triggers. Start by recording when your headaches or migraines occur and try to identify specific foods, weather conditions or physical, emotional and/or mental disturbances that may occur prior to the onset of your headache or migraine.
