i have the visual flashes too. ive had them for 13 months now sometimes its worse than other times but it shows know signs of going away. i cant believe i just type 13 months wtf its depressing but ive learned to just deal with them. they are the tell tale sign im still concussed i think

anyway im 99% sure the flashes are because of migraines. my nuerologist said im stuck in a migraine state. ive tried meds but no luck so now im basically just living day to day hoping it goes away when i wake up one day

all my other symptoms are gone except for my visual ones
