VA Disability provides monthly cash payments to veterans who are disabled due to an event that happened during military service.  The VA provides a different percentage of disability rating for various conditions.  These ratings are combined to make an overall disability rating for the veteran upon which disability payment are computed.  Some injuries, such as amputations, allow for easy diagnosis, while other injuries, such as migraines and post traumatic stress disorder, do not have readily identifiable symptoms.

The disability ratings provided to a veteran who Has migraines, depend on the frequency, continuity, and severity of the headaches.  Frequency refers to how often a headache develops, e.g. once a week or several times a day.  Continually refers to how many years the headaches have found to be present.  Severity refers to whether the headache knocks the veteran out for days or is just a slight annoyance,

There is little medical evidence can due to diagnose a migraine.  There is no definitive proof of a headache provided by a machine.  Lay evidence from family and friends is often useful in proving the frequency, continuity, and severity of headaches.  Statements from family and friends that the veteran misses special occasions often due to persistent headaches can be good evidence to prove service connection.  Showing that headaches are much more severe and frequent can be the difference between a 10% rating and a 50%  rating, and can lead to a significant increase in benefits.

While it is possible for a veteran to compile the needed evidence themselves to prove a higher rating for migraines, hiring an experienced attorney to appeal the case  is useful if a veteran has been denied.
