This study will evaluate the effectiveness of Treximet when taken for post traumatic headache
by measuring any change in the number of headache days or any change in a subject's ability
to think following treatment with study medication. Eligible subjects will complete 3 visits.
Following Visit 1, subjects will treat with their usual medication and document headache
symptoms and therapy in a Headache Diary. After 30 days, subjects will return for Visit 2 and
be randomized (like the flip of a coin) to receive Treximet or matching placebo to treat at
the same time each day. Treximet will be provided to treat any headache that occurs. Subjects
will complete a daily Diary. After 30 days, subjects will exit the study at Visit 3.
