Have you had any work done on the phone recently? Any recent drops or water damage?
The most common cause of this would be a bad digitizer. Its a very simple repair if you feel froggy enough to do it, iFixit even sells a great kit to do the repair with. If its not the digitizer, then you would be looking at a more complicated repair of some board level components. I highly doubt this is the case unless the phone has water damage.
If it were me, I'd replace the LCD and see if that fixes the problem as its the cheapest thing to replace. If that doesn't fix it, I would take it to a reputable repair shop and have them diagnose the issue.
One possible solution is a hard reset. This can be performed by holding the power and home button simultaneously until the phone turns off and the Apple logo appears. If that does not resolve the issue then the next step would be trying a new LCD/Digitizer.
