Migraine headaches are frequenty brought on by light, as well as aggravating the headaches. My only concern is the fact that this started after a concussion and that would seem pretty unusual to begin getting migraines.

You are under the care of a neurologist; but might want to get another opinion. I would assume you had an MRI after the concussion; especially since the headaches continue. If you have not; would be a good idea. You are treating the pain, which the treatment could actually be causing the pain. When I had rebound headaches (had used Midrin and Bufferin for years), I would take a Midrin, it would subside for an hour or so and then come on even worse; then would take another one; this would continue throughout the day/night. This is what lead to the rebound. The headache were daily. I finally had to get off all the pain meds to find out how much was caused by rebound. That was a very painful time. Not sure in your case, because of concussion, it is a good idea. But that's what rebound headaches are...daily and within an hour or two, back again.

When Imitrex came on the market, it was unbelievable how this helped. I learned my lesson as well, not to overdo and since I had eleminited the rebound effect by stoping the Midrin and Bufferin, the Imitrex worked. I have been taking the imitrex for at least 10 years.

Again, I would suggest getting another opinion and an MRI if you have not already had one.
