I have vertical, flickering lines on the side of my screen?

I have a macbook pro, 13in with retnia display, early 2015. I purchased it in August of 2015 and have fairly careful with, have never gotten liquids on it etc. However, today my screen began flickering randomly at times, and several times there has been a solid stripe of lines, about 2 inches thick, blocking my view of the that part of the screen. Restarting the computer several times causes the solid lines to become clear and flicker rapidly. Go to mymacissues.tumblr.com to see videos of the problem if you wish. As I am typing, it has happened again. Luckily I have applecare and live fairly close to an apple store, but I would like to be able to fix the issue without having to go there. Any suggestions would be appreciated!
