I had a car accident in March 2012, I hit my head and left shoulder, but at the time I didn't realize how hard I hit. I did go to an orthopaedic Doctor and had xrays which were normal ( the next day) later had and MRI which was normal. I started with some mild headaches which I thought nothing of took OTC medication which helped then.
Five months later while working I lost usage of my left side and could not walk or use that side for 3 weeks. I was given TPA and was in ICU for 3 days and was diagnoised with an Atypical Migraine that I had for 8 months straight. I was put on several oral medications with NO relief and finally I was told to try BOTOX which I did and it helped. All my MRI,MRA, and Ct were all normal.
My questions to you is. Can a head injury cause a headache 5 months later?
Good question! Usually when I hear such a story I uncover the fact that the patient has a previous history of head injuries. Some may be mild, others are sports related injuries and I recently saw an 86 year old lady who admitted to falling out of a tree when in her 40s!
Head injuries are cumulative. Usually one last insult to the brain is enough to start causing the headaches.
As to what started the migraine months after an injury, it could have been anything...stress perhaps? Your menstrual cycle? Whatever it was, clearly your brain had an injury and something pushed it "over the edge" so to speak into a migraine.
Keep up the Botox if it is helping. Studies have shown the longer some patients get Botox, the better it works
