Hi, Thanks for writing in. I feel your friend needs a complete evaluation of her headache and discussion with old imaging reports. Head injury with multiple clots inside is a serious condition and it is important to know the exact sequence of events in her rehabilitation. People with clots in the brain require close monitoring and specialist care by a neurological team. Naxdom contains naproxen and is a good pain reliever. She needs to be assessed and the episodes of headache are to be studied in details. If there is any situation that increases her headaches then that must be avoided. A follow up brain CT scan might be required to know how much of her brain has made a recovery and if she needs to continue the medications. She can also try doing mind relaxation exercises if that can help decrease the frequency and intensity of her headaches.
