Touch screen gone whacky

After using the touch screen with wet hands, the touch sensitivity has screwed up on the left side of the display. Water had properly dried up but the touch wasn't working properly. But gradually the condition of the touch turned better but a long patch of the left side of the display doesn't detect touches properly/accurately/at all anymore. I have changed roms and all but it's a hardware problem so nothing fixes it. I used a developer option "pointer location" to give you guys an idea on how the condition of the touch is. Look at the left side. A long patch shows that touches aren't detected in that area. The patches are kinda circular.




What do I do now? :(
