Panic attacks appear suddenly without discretion and often are very intense. The fear that is associated with this condition will cause a person to experience anxiety to the point they will have a panic attack headache.
People who regularly suffer from migraines are the ones most susceptible to having a panic attack headache. Migraines are intense and severe and often are debilitating to the point of putting a person in bed for days. The intense pain and sensitivity to light make this type of headache the most difficult to bear.
Many studies have shown that migraines usually have some sort of a trigger. In cases of people who suffer from panic attacks the attack is often the trigger that sets off the headache.
