Any doctors out there?

I have been seeing flashing lights whenever I close my eyes. Its been going on for im going to say a month. It makes it difficult to fall asleep so when I actually do I end up sleeping up to 12 hours because it takes the pain away. When im awake it's there as well almost like a constant migraine... I was diagnosed with a brain AVM last year and had a stroke last November so im on tons of medication. Im 18 and a female. I would like to know if this is something I should be worried about and have my mom take me to the hospital sooner rather than later or if there's an easy fix for it.
