about a month ago I was riding my bike and was about to cross an intersection when a taxi suddenly put itself in the middle of the bike line, I almost crashed directly but was able to swerve to the right and slow down while also changing the way I was going to impact it and reduced the severity of my inguries significantly, the thing is that I didn't go to a hospital since I didn't break any bones, but now I feel like I might have gotten brain damage from it. Is it to late to go to a doctor or do anything to regain my faculties?
