Red Vertical lines and a black bar.

So recently my iPhone 6 fell approximately 8 inches from my knee on a gym floor, and when I picked it up it had blue lines running vertically on the screen, and the lines only seem to appear wherever bright lights on the screen are. Later, a large black bar ran up the right side of my screen that is about an inch thick. I can still tap apps and things behind the black line but I cannot see them. All of this happened yesterday, and just recently the blue lines have turned a redish pink color. I imagine I probably just have to replace the screen, but does it sound like there is anything crazy bad about my phone? Thank you in advance!
