Vertical lines,unresponsive touch,contacts not displayed in text notif

I've read about this problem before but have additional concern. So phone was dropped, white vertical lines only on the left side of screen, touch screen unresponsive. However, in addition, I noticed that I'm still receiving text notifications from friends but their numbers are displayed instead of their contact names. Should I be worried that their is a more concerning issues than the digitizer being knocked loose? I wanted to save my pics to my computer before screwing around with my phone but I just (as in two days ago) put a lock pass code on my phone and can't get access since my touchscreen isn't working! :( The buttons on the phone are still working btw.
